Ns_DbDML

Overview

Execute an SQL DML statement

Syntax

    int Ns_DbDML(
    	Ns_DbHandle *handle,
    	char        *sql
    );

Description

The Ns_DbDML function executes SQL that should be a data manipulation language statement such as an insert or update, or data definition language such as a create table. If the statement was executed successfully, Ns_DbDML returns NS_OK. If the statement results in rows being returned or a other database error, Ns_DbDML returns NS_ERROR. Detailed error messages may have accumulated in an internal buffer in the Ns_DbHandle. These errors can be conveyed back to the user through the Ns_DbReturnError function.

Example

    
    Ns_DbHandle *handle;
    int status;
    if ((handle = Ns_DbPoolGetHandle("aPoolName")) != NULL) {
    	status = Ns_DbDML(handle, 
    		"insert into aTable (colName1,colName2) values (1,2)");
    	if (status != NS_OK) {
    		/* handle error condition */
    	}	
    }
