You can import metadata from your flat file data sources and create the metamodels required to query your data in minutes. Using the steps below you will define your flat file data source, configure your parsing paramaters for the flat file, generate a source model containing the standard Teiid flat file procedure and create view tables containing the SQL defining the column data in your flat file.
Teiid supports Flat Files as data sources. Teiid Designer provides an Import wizard designed to assist in creating the metadata models required to access the data in your flat files. As with Designer's JDBC, Salesforce and WSDL importers, the Flat File importer is based on utilizing a specific Data Tools Connection Profile.
The results of the importer will include a source model containing the getTextFiles() procedures supported by Teiid.
The importer will also create a new view model containing a view table for your selected flat file source file. Within the view table will be generated SQL transformation containing the "getTextFiles()" procedure from your source model as well as the column definitions and parameters required for the Teiid TEXTTABLE() function used to query the data file. You can also choose to update an existing view model instead of creating a new view model.
The TEXTTABLE function, as defined in the Teiid documentation, processes character input to produce tabular ouptut. It supports both fixed and delimited file format parsing. The function itself defines what columns it projects. The TEXTTABLE function is implicitly a nested table and may be correlated to preceeding FROM clause entries.
TEXTTABLE(expression COLUMNS <COLUMN>, ... [DELIMITER char] [(QUOTE|ESCAPE) char] [HEADER [integer]] [SKIP integer]) AS name
Teiid Designer will construct the full SQL statement for each view table in the form:
SELECT A.Name, A.Sport, A.Position, A.Team, A.City, A.StateCode, A.AnnualSalary FROM (EXEC PlayerDataSource.getTextFiles('PlayerData.txt')) AS f, TEXTTABLE(f.file COLUMNS Name string, Sport string, Position string, Team string, City string, StateCode string, AnnualSalary string HEADER 2 SKIP 3) AS ATo import from your flat file source follow the steps below.
Step 1 - In Model Explorer choose the File > Import action
in the toolbar or select a project, folder or
model in the tree and choose Import...Step 2 - Select the import option Teiid Designer > File Source (Flat) >> Source and View Model and click Next>
Step 3 - Select existing or previous connection profile from the drop-down selector or press button to launch the New Connection Profile dialog (See Eclispe Data Tools documentation) or to modify/change an existing connection profile prior to selection. Note that the Flat File Source selection list will be populated with only Flat File connection profiles.
After selecting a Connection Profile, the file contents of the folder defined in the connection profile will be displayed in the Available Data Files panel. Check the the data file you wish to process. The data from this file, along with your custom import options, will be used to construct a view table containing the required SQL transformation for retrieving your data and returning a result set.
Lastly enter or unique source model name in the Source Model Definition section at the bottom of the page or select an existing source model using the browse button. Note the Model Status section which will indicate the validity of the model name, whether the model exists or not and whether the model already contains the getTextFiles() procedure. In this case, the source model nor the procedure will be generated.
When finished with this page, click Next>.
Step 4 - The next page, titled Flat File Column Format Definition, requires defining the format of your column data in the file. The options are and . This page contains a preview of the contents of your file to aid in determining the format. The wizard defaults to displaying the first 20 lines, but you can change that value if you wish.
When finished with this page, click Next>.
Step 5a : Character Delimited Option - The primary purpose of this importer is to help you create a view table containing the transformation required to query the user-defined data file. This page presents a number of options you can use to customize the Generated SQL Statement , shown in the bottom panel, for the character delimited option. Specify header options (Column names in header, header line number and first data line number), Parse selected row, changed character delimiter and edit the TEXTTABLE() function options. See the Teiid User's Guide for details on the TEXTTABLE() function.
If columns names are not defined in a file header or if you wish to modify or create custom columns, you can use the , , , to manage the column info in your SQL.
When finished with this page, click Next>.
To aid in determining if your parser settings are correct you can select a data row in your File Contents Preview section and click the Parse Selected Row button. A dialog will be displayed showing the list of columns and the resulting column data. If your column data is not what you expected, you'll need to adjust your settings accordingly.
Step 5b : Fixed Column Width Option - The primary purpose of this importer is to help you create a view table containing the transformation required to query the user-defined data file. This page presents a number of options you can use to customize the Generated SQL Statement , shown in the bottom panel, for the fixed column width option. Specify header options (Column names in header, header line number and first data line number), Parse selected row, changed character delimiter and edit the TEXTTABLE() function options. See the Teiid User's Guide for details on the TEXTTABLE() function.
If columns names are not defined in a file header or if you wish to modify or create custom columns, you can use the , , , to manage the column info in your SQL.
You can also utilize the cursor postion and text length values in the upper left panel to determine what your column widths are in your data file.
When finished with this page, click Next>.
Step 6 - On the View Model Definition page, select the target folder location where your new view model will be created. You can also select an existing model for your new view tables. Note the Model Status section which will indicate the validity of the model name, whether the model exists or not. Lastly, enter a unique, valid view table name. Press Finish to generate your models and finish the wizard.
When your import is finished your source model will be opened in an editor and show a diagram containing the your getTextFiles() procedure.
In addition, the view model will be opened in an editor and will show the generated view tables containing the completed SQL required to access the data in your flat file using the "getTextFiles" procedure above and the Teiid TEXTTABLE() function. The following figure is an example of a generated view table.
Teiid supports XML Files as data sources. You can import from these data sources and create the metamodels required to query your data in minutes. Using the steps below you will define your flat file data source, configure your parsing paramaters for the xml data file, generate a source model containing the required Teiid procedure and create a view table containing the SQL defining the column data in your xml data file.
As with Designer's JDBC, Salesforce and WSDL importers, the XML File importer is based on utilizing a specific Data Tools Connection Profile.
The results of the importer will include a source model containing the getTextFiles() procedure or invokeHTTP() procedure which are both supported by Teiid.
The importer will also create a new view model containing a view table for your selected flat file source file. Within the view table will be generated SQL transformation containing the "getTextFiles()" procedure from your source model as well as the column definitions and parameters required for the Teiid XMLTABLE() function used to query the data file. You can also choose to update an existing view model instead of creating a new view model.
The XMLTABLE function uses XQuery to produce tabular ouptut. The XMLTABLE function is implicitly a nested table and may be correlated to preceeding FROM clause entries. XMLTABLE is part of the SQL/XML 2006 specification.
XMLTABLE([<NSP>,] xquery-expression [<PASSING>] [COLUMNS <COLUMN>, ... )] AS name
COLUMN := name (FOR ORDINALITY | (datatype [DEFAULT expression] [PATH string]))
Teiid Designer will construct the full SQL statement for each view table in the form:
SELECT A.entryDate AS entryDate, A.internalAudit AS internalAudit FROM (EXEC CCC.getTextFiles('sample.xml')) AS f, XMLTABLE(XMLNAMESPACES('http://www.kaptest.com/schema/1.0/party' AS pty), '/pty:students/student' PASSING XMLPARSE(DOCUMENT f.file) COLUMNS entryDate FOR ORDINALITY, internalAudit string PATH '/internalAudit') AS ATo import from your XML data file source follow the steps below.
Step 1 - In Model Explorer choose the File > Import action
in the toolbar or select a project, folder or
model in the tree and choose Import...Step 2 - Select the import option Teiid Designer > File Source (XML) >> Source and View Model and click Next>
Step 3 - The next page of the wizard allows selection of the XML Import mode that specifies whether the XML file is local or remote. The description at the top describes what operations this wizard will perform. Select either the XML file on local file system or XML file via remote URL and click Next>
Step 4 - Select existing or previous connection profile from the drop-down selector or press button to launch the New Connection Profile dialog (See Eclispe Data Tools documentation) or to modify/change an existing connection profile prior to selection.
After selecting a Connection Profile, the XML data file from the connection profile will be displayed in the Available Data Files panel. Check the the data file you wish to process. The data from this file, along with your custom import options, will be used to construct a view table containing the required SQL transformation for retrieving your data and returning a result set.
Lastly enter or unique source model name in the Source Model Definition section at the bottom of the page or select an existing source model using the browse button. Note the Model Status section which will indicate the validity of the model name, whether the model exists or not and whether the model already contains the getTextFiles() procedure. In this case, the source model nor the procedure will be generated.
When finished with this page, click Next>.
Step 5 - The primary purpose of this importer is to help you create a view table containing the transformation required to query the user-defined data file. This page presents a number of options you can use to customize the Generated SQL Statement , shown in the bottom panel. The to panel contains an XML tree view of your file contents and actions/buttons you can use to create column entries displayed in the middle, Column Information panel.
To create columns, select a root XML element and right-click select action. This populates the root path value. Next, select columns in the tree that you wish to include on your query and select button. You can also modify or create custom columns, by using the , , , to manage the column info in your SQL.
Note that the property value for a column is the selected element's path relative to the defined root path. If no root path is defined all paths are absolute. Each column entry requires a datatype and an optional default value. See the Teiid User's Guide for details on the XMLTABLE() function.
When finished with this page, click Next>.
Step 6 - On the View Model Definition page, select the target folder location where your new view model will be created. You can also select an existing model for your new view tables.

You can create a Relational model by selecting an existing Web Services Connection Profile defined by a WSDL file in your workspace or defined by a URL. Designer will interpret the WSDL, locate any associated or dependent XML schema files, generate a physical model to invoke the service, and generate virtual models containg procedures to build and parse the XML declared as the service messages.
The sample WSDL for this section defines the following:
A single wsdl:service named Share_BSM_Real_Time_Data_Design_Server_RealTimeData_portService
A single wsdl:port named Share_BSM_Real_Time_Data_Design_Server_RealTimeData_portPort0"
A single wsdl:portType named Share_BSM_Real_Time_Data_Design_Server_RealTimeData_portPortType
A single wsdl:operation named OnHand
To create relational models from WSDL use the steps below.
Step 1 - In Model Explorer choose the File > Import action in the toolbar or select a project, folder or model in the tree and choose Import...
Step 2 - Select the import option Teiid Designer > WSDL File or URL >> Source Model and click Next>
Step 3 - On the next page select an existing Web Service Connection Profile from the list, or click the New Button to create a new profile.
Step 4 - When the connection profile is selected, you'll be required to validate your WSDL via the Validate WSDL button (see above figure). If the WSDL is not valid, or does not comply with WS-I 1.0, the validation failures will be displayed in an error dialog.
Step 5 - Select a model project in the Target Workspace Folder field via the Browse... button. Click Next> when the target is defined.
Step 6 - The next page allows you to selected individual Web Service Operations to model. The default behavior of this page selects all available operations in the tree. Operations can be de-selected if they are not being modeled. The Selection Details editor displays static information about the operation such as the names of the input and output messages, and faults thrown by the operation.
Step 7 - Click Finish. After generation the new models can be found in the specified location in your workspace.
In the Model Explorer you can see the importer created the following:
A single physical model containing a single procedure called invoke. This model and procedure correspond to the single port declared in the WSDL. For a WSDL with multiple wsdl:port declarations the importer would create a physical model with an invoke procedure for each wsdl:port declaration. This facilitates binding each physical model to its own Teiid WebService Connector and allowing the connector to supply the endpoint.
A single view model containing a catalog named after the operation declared in the WSDL. For a WSDL with multiple wsdl:operation declarations, the importer would create multiple catalogs. The catalog contains procedure declarations that use the SQLXML calls supported by Teiid to create and parse the XML defined as the operation messages.
The user can now use the procedures defined by the importer in a higher level view model that builds the request, executes the service via the invoke procedure, and extracts the results from the response.
You can create a Web Service model by selecting a WSDL file in your workspace, importing WSDL files from the file system or by defining a URL. The Teiid Designer will interpret the WSDL, locate any associated or dependent XML Schema files, generate an XML View of the schema components and create a Web Service model representing the interfaces and operations defined in the WSDL.
There are three options for selecting the WSDL for your Web Service generation
Workspace Location
File System Location
URL
Detailed steps for each of these options is described below, as well as a description of how the wizard handles WSDL errors.
