    public interface ProcedureCall
    extends CommonQueryContract, SynchronizeableQuery, jakarta.persistence.StoredProcedureQuery, NameableQuery, AutoCloseable
    Defines support for executing database stored procedures and functions.

    Note that here we use the terms "procedure" and "function" as follows:

    • procedure is a named database executable we expect to call via : {call procedureName(...)}
    • function is a named database executable we expect to call via : {? = call functionName(...)}
    Unless explicitly specified, the ProcedureCall is assumed to follow the procedure call syntax. To explicitly specify that this should be a function call, use markAsFunctionCall(int). JPA users could either:
    • use storedProcedureQuery.unwrap( ProcedureCall.class .markAsFunctionCall()
    • set the FUNCTION_RETURN_TYPE_HINT hint (avoids casting to Hibernate-specific classes)

    When using function-call syntax:

    • parameters must be registered by position (not name)
    • The first parameter is considered to be the function return (the `?` before the call)
    • the first parameter must have mode of OUT, INOUT or REF_CURSOR; IN is invalid

    In some cases, based on the Dialect, we will have other validations and assumptions as well. For example, on PGSQL, whenever we see a REF_CURSOR mode parameter, we know that:

    • this will be a function call (so we call markAsFunctionCall(int) implicitly) because that is the only way PGSQL supports returning REF_CURSOR results.
    • there can be only one REF_CURSOR mode parameter

      • FUNCTION_RETURN_TYPE_HINT

        static final String FUNCTION_RETURN_TYPE_HINT
        The hint key (for use with JPA's "hint system") indicating the function's return JDBC type code (aka, Types code)

    • Method Detail

      • getProcedureName

        String getProcedureName()
        Get the name of the stored procedure (or function) to be called.
        Returns:
        The procedure name.
      • isFunctionCall

        boolean isFunctionCall()
        Does this ProcedureCall represent a call to a database FUNCTION (as opposed to a PROCEDURE call)? NOTE : this will only report whether this ProcedureCall was marked as a function via call to markAsFunctionCall(int). Specifically will not return true when using JPA query hint.
        Returns:
        true indicates that this ProcedureCall represents a function call; false indicates a procedure call.
      • markAsFunctionCall

        ProcedureCall markAsFunctionCall​(int sqlType)
        Mark this ProcedureCall as representing a call to a database function, rather than a database procedure.
        Parameters:
        sqlType - The Types code for the function return
        Returns:
        this, for method chaining
