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

Parameters

Table 1 SQLSetStmtAttr parameters

Keyword

Description

StatementHandle

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, or a driver-specified value. If the ValuePtr parameter is driver-specific value, it may be a signed integer.

StringLength

If ValuePtr points to a string or a binary buffer, StringLength is 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 that 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. This value may also be returned by other APIs.

Precautions

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