SQLExtendedBind - Bind an Array of Columns

Purpose

Specification: DB2 CLI 6

SQLExtendedBind() is used to bind an array of columns instead of using repeated calls to SQLBindCol() or SQLBindParameter().

Syntax

SQLRETURN    SQLExtendedBind (    
                              SQLHSTMT          StatementHandle,
                              SQLSMALLINT       fBindCol,
                              SQLSMALLINT       cRecords,
                              SQLSMALLINT *     pfCType,
                              SQLPOINTER  *     rgbValue,
                              SQLINTEGER  *     cbValueMax,

                              SQLSMALLINT *     pibScale ) ;

Function Arguments

Table 61. SQLExtendedBind() Arguments

Data Type Argument Use Description

Usage

This function is used to replace multiple calls to SQLBindCol() or SQLBindParameter().

The argument fBindCol determines whether this function call is used to associate (bind):

parameter markers in an SQL statement (as with SQLBindParameter()) - fBindCol = SQL_FALSE
columns in a result set (as with SQLBindCol()) - fBindCol = SQL_TRUE

For more information (including allowed argument values), see SQLBindCol - Bind a Column to an Application Variable or LOB Locator and SQLBindParameter - Bind A Parameter Marker to a Buffer or LOB Locator

Return Codes

SQL_SUCCESS
SQL_SUCCESS_WITH_INFO
SQL_ERROR
SQL_INVALID_HANDLE

Diagnostics

Table 62. SQLExtendedBind() SQLSTATEs

SQLSTATE Description Explanation
07006 Invalid conversion. The conversion from the data value identified by a row in the pfCType argument to the data type identified by the pfParamType argument is not a meaningful conversion. (For example, conversion from SQL_C_DATE to SQL_DOUBLE.)
07009 Invalid descriptor index The value specified for the argument cRecords exceeded the maximum number of columns in the result set.
40003 08S01 Communication link failure. The communication link between the application and data source failed before the function completed.
58004 Unexpected system failure. Unrecoverable system error.
HY001 Memory allocation failure. DB2 CLI is unable to allocate memory required to support execution or completion of the function.
HY003 Program type out of range. A row in pfParamType or pfSQLType was not a valid data type or SQL_C_DEFAULT.
HY004 SQL data type out of range. The value specified for the argument pfParamType is not a valid SQL data type.
HY009 Invalid argument value. The argument rgbValue was a null pointer and the argument cbValueMax was a null pointer, and pfParamType is not SQL_PARAM_OUTPUT.
HY010 Function sequence error. The function was called while in a data-at-execute (SQLParamData(), SQLPutData()) operation.
The function was called while within a BEGIN COMPOUND and END COMPOUND SQL operation.
HY013 Unexpected memory handling error. DB2 CLI was unable to access memory required to support execution or completion of the function.
HY021 Inconsistent descriptor information The descriptor information checked during a consistency check was not consistent.
HY090 Invalid string or buffer length. The value specified for the argument cbValueMax is less than 1 and the argument the corresponding row in pfParamType or pfSQLType is either SQL_C_CHAR, SQL_C_BINARY or SQL_C_DEFAULT.
HY093 Invalid parameter number. The value specified for a row in the argument pfCType was less than 1 or greater than the maximum number of parameters supported by the server.
HY094 Invalid scale value. The value specified for pfParamType was either SQL_DECIMAL or SQL_NUMERIC and the value specified for DecimalDigits was less than 0 or greater than the value for the argument pcbColDef (precision).
The value specified for pfParamType was SQL_C_TIMESTAMP and the value for pfParamType was either SQL_CHAR or SQL_VARCHAR and the value for DecimalDigits was less than 0 or greater than 6.
HY104 Invalid precision value. The value specified for pfParamType was either SQL_DECIMAL or SQL_NUMERIC and the value specified by pcbColDef was less than 1.
HY105 Invalid parameter type. pfParamType is not one of SQL_PARAM_INPUT, SQL_PARAM_OUTPUT, or SQL_PARAM_INPUT_OUTPUT.
HYC00 Driver not capable. DB2 CLI recognizes, but does not support the data type specified in the row in pfParamType or pfSQLType.
A LOB locator C data type was specified, but the connected server does not support LOB data types.

HY093	Invalid parameter number.	The value specified for a row in the argument `pfCType` was less than 1 or greater than the maximum number of parameters supported by the server.
HY094	Invalid scale value.	The value specified for `pfParamType` was either SQL_DECIMAL or SQL_NUMERIC and the value specified for `DecimalDigits` was less than 0 or greater than the value for the argument `pcbColDef` (precision). The value specified for `pfParamType` was SQL_C_TIMESTAMP and the value for `pfParamType` was either SQL_CHAR or SQL_VARCHAR and the value for `DecimalDigits` was less than 0 or greater than 6.
HY104	Invalid precision value.	The value specified for `pfParamType` was either SQL_DECIMAL or SQL_NUMERIC and the value specified by `pcbColDef` was less than 1.
HY105	Invalid parameter type.	`pfParamType` is not one of SQL_PARAM_INPUT, SQL_PARAM_OUTPUT, or SQL_PARAM_INPUT_OUTPUT.
HYC00	Driver not capable.	DB2 CLI recognizes, but does not support the data type specified in the row in `pfParamType` or `pfSQLType`. A LOB locator C data type was specified, but the connected server does not support LOB data types.
