Modifying 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 TableauCRM Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"INSERT INTO Dataset_Opportunity (CloseDate) VALUES ('12-31-2017')", 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 TableauCRM Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"UPDATE Dataset_Opportunity SET CloseDate='12-31-2017' WHERE StageName='Closed Won')", 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 TableauCRM Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"DELETE FROM Dataset_Opportunity WHERE Id='25')", SQL_NTS);  
SQLINTEGER  rowCount = 0;
SQLRowCount(hstmt, &rowCount);
