If you want to execute a query you will need to specify a handle (SQL_HANDLE_STMT) for a SQL-statement. In order to get one you have to allocate one with SQLAllocHandle . Then you have to think about the SQL statement you want to execute.

Mar 2, 2012 · ODBC is an open specification for providing application developers with a predictable API with which to access Data Sources. Data Sources include SQL Servers and any Data Source with an ODBC Driver. Why use ODBC? The ODBC API, as outlined by X/Open and ISO, is availible on all major platforms.

use odbc_api::{Connection, ConnectionOptions, Environment, IntoParameter, sys::{AttrConnectionPooling, AttrCpMatch}}; use std::{sync::OnceLock, time::Duration}; use …

Apr 13, 2012 · I am using unixODBC driver in centOS machine and my database is postgresql. I did a research on how to execute a sql asynchronously using odbc api. I found SQLSetStmtAttr api can be used to execute the sql statement asynchronously.

First thing you will need is a variable of type SQLHENV. This is a handle (pointer) to an internal ODBC structure which holds all informationen about the ODBC environment. Without a handle of that kind you won't be able do to very much. To get this handle you call SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &V_OD_Env).

Aug 10, 2021 · I am trying to run a query on sql server (source) using isql on the client server. Everything worked before the rhel6 to rhel7 upgrade on the client server. I am able to connect to sql server just not run any queries. I verified that all the drivers are there and none of the odbc files were changed.

Dec 7, 2017 · I want to execute multiple queries in an ODBC DSN Connection to MySQL using UnixODBC. For example as below: I am using SQLExecDirect() to trigger the command and then SQLFetch() to fetch the resultset. If I execute just one query it works fine.

ODBC is an open specification for providing application developers with a predictable API with which to access Data Sources. Data Sources include SQL Servers and any Data Source with an ODBC Driver. The unixODBC Project goals are to develop and promote unixODBC to be the definitive standard for ODBC on non MS Windows platforms.

This tool is designed for more advanced uses of unixODBC. You can use isql to test a connection but it is designed to be used by those experienced with the Structured Query Language (SQL). You probably will not want to use this tool if you are unfamiliar with SQL. isql allows you to; 1. connect to your Data Source (using a DSN)
