説明

The ODBC_SQLSetDescRec command sets multiple descriptor fields that affect the data type and buffer bound to a column or parameter data.

StmtID is a valid statement ID returned by ODBC_SQLAllocStmt.

Descriptor records are numbered from 1, with recNumber equal to 0 being the bookmark record. The recNumber argument must be less than or equal to the value of SQL_DESC_COUNT. If recNumber is less than or equal to SQL_DESC_COUNT but the row does not contain data for a column or parameter, a call to ODBC_SQLSetDescRec will return the default values of the fields.

recNumber is the descriptor record number.

type is the SQL_DESC_TYPE field for the descriptor record.

subType is the SQL_DESC_DATETIME_INTERVAL_CODE field for the descriptor record (for records whose type is SQL_DATETIME or SQL_INTERVAL).

length is the SQL_DESC_OCTET_LENGTH field for the descriptor record.

precision is the SQL_DESC_PRECISION field for the descriptor record.

scale is the SQL_DESC_SCALE field for the descriptor record.

dataPtr is the SQL_DESC_DATA_PTR field for the descriptor record.

stringLengthPtr is the SQL_DESC_OCTET_LENGTH_PTR field for the descriptor record.

indicatorPtr is the SQL_DESC_OCTET_INDICATOR_PTR field for the descriptor record.

Function Results

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.
