SQLBindParameter
Function
SQLBindParameter is used to associate (bind) parameter markers in an SQL statement to a buffer.
Prototype
1 2 3 4 5 6 7 8 9 10 | SQLRETURN SQLBindParameter(SQLHSTMT StatementHandle, SQLUSMALLINT ParameterNumber, SQLSMALLINT InputOutputType, SQLSMALLINT ValuetType, SQLSMALLINT ParameterType, SQLULEN ColumnSize, SQLSMALLINT DecimalDigits, SQLPOINTER ParameterValuePtr, SQLLEN BufferLength, SQLLEN *StrLen_or_IndPtr); |
Parameter
Keyword |
Description |
---|---|
StatementHandle |
Statement handle. |
ParameterNumber |
Parameter marker number, starting at 1 and increasing in an ascending order. |
InputOutputType |
Input/output type of the parameter. |
ValueType |
C data type of the parameter. |
ParameterType |
SQL data type of the parameter. |
ColumnSize |
Size of the column or expression of the corresponding parameter marker. |
DecimalDigits |
Digital number of the column or the expression of the corresponding parameter marker. |
ParameterValuePtr |
Pointer to the storage parameter buffer. |
BufferLength |
Size of the ParameterValuePtr buffer in bytes. |
StrLen_or_IndPtr |
Pointer to the length or indicator of the buffer. If StrLen_or_IndPtr is null, no length or indicator is used. |
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 SQLBindCol returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, the application can then 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.
