Updating Data

The following code examples show how to use data modification statements.

Procedure for Updates

Use SQLExecDirect to execute data manipulation statements and use the SQLRowCount function to obtain the affected rows.

INSERT

To insert updates:

SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv); 
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0); 
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc); 
SQLDriverConnect(hdbc, 0, (SQLCHAR*)"Dsn=CData Acumatica Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"INSERT INTO Events (location_displayName) VALUES ('Town Hall Grille')", SQL_NTS);  
SQLINTEGER  rowCount = 0;
SQLRowCount(hstmt, &rowCount);

UPDATE

To retrieve updates:

SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv); 
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0); 
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc); 
SQLDriverConnect(hdbc, 0, (SQLCHAR*)"Dsn=CData Acumatica Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"UPDATE Events SET location_displayName='Town Hall Grille' WHERE Id='Jq74mCczmFXk1tC10GB')", SQL_NTS);  
SQLINTEGER  rowCount = 0;
SQLRowCount(hstmt, &rowCount); 

DELETE

To delete updates:

SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &henv); 
SQLSetEnvAttr(henv, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0); 
SQLAllocHandle(SQL_HANDLE_DBC, henv, &hdbc); 
SQLDriverConnect(hdbc, 0, (SQLCHAR*)"Dsn=CData Acumatica Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"DELETE FROM Events WHERE Id='Jq74mCczmFXk1tC10GB')", SQL_NTS);  
SQLINTEGER  rowCount = 0;
SQLRowCount(hstmt, &rowCount);
