Method Detail

getSQLType

public static final int getSQLType(String typeName)

This method is used to obtain a short indicating JDBC SQL type for any object. The short values that give the type info are from java.sql.Types.

Parameters:

typeName - of the teiid type.

Returns:

A short value representing SQL Type for the given java type.

getSQLTypeFromClass

public static final int getSQLTypeFromClass(String className)

Get sql Type from java class type name. This should not be called with runtime types as Clob and Blob are represented by ClobType and BlobType respectively.

Parameters:

className -

Returns:

int

getSQLTypeFromRuntimeType

public static final int getSQLTypeFromRuntimeType(Class<?> type)

Get the sql type from the given runtime type

Parameters:

type -

Returns:

the SQL type code

getJavaClassName

public static final String getJavaClassName(int jdbcSQLType)

This method is used to obtain a the java class name given an int value indicating JDBC SQL type. The int values that give the type info are from java.sql.Types.

Parameters:

jdbcSQLType - value giving the SQL type code.

Returns:

A String representing the java class name for the given SQL Type.
