SQLSetStmtAttr

Function

SQLSetStmtAttr sets attributes related to a statement.

Prototype

SQLRETURN SQLSetStmtAttr(SQLHSTMT      StatementHandle
                         SQLINTEGER    Attribute,
                         SQLPOINTER    ValuePtr,
                         SQLINTEGER    StringLength);

Parameter

Table 1 SQLSetStmtAttr parameters

Keyword

Description

StatementtHandle

Statement handle.

Attribute

Attribute to set.

ValuePtr

Pointer to the Attribute value. ValuePtr depends on the Attribute value, and can be a 32-bit unsigned integer value or a pointer to a null-terminated string, a binary buffer, and a driver-specified value. If ValuePtr parameter is driver-specific value, it may be signed integer.

StringLength

If ValuePtr points to a string or a binary buffer, this parameter should be the length of *ValuePtr. If ValuePtr points to an integer, StringLength is ignored.

Return Values

  • SQL_SUCCESS indicates that the call succeeded.

  • SQL_SUCCESS_WITH_INFO indicates some warning information is displayed.

  • SQL_ERROR indicates major errors, such as memory allocation and connection failures.

  • SQL_INVALID_HANDLE indicates that invalid handles were called. Values returned by other APIs are similar to the preceding values.

Precautions

If SQLSetStmtAttr returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, the application can then call SQLGetDiagRec, set HandleType and Handle to SQL_HANDLE_STMT and StatementHandle, and obtain the SQLSTATE value. The SQLSTATE value provides the detailed function calling information.
