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 YouTubeAnalytics Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"INSERT INTO Groups (ContentDetails_ItemType) VALUES ('youtube#channel')", 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 YouTubeAnalytics Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"UPDATE Groups SET ContentDetails_ItemType='youtube#channel' WHERE Id='S')", 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 YouTubeAnalytics Source;", SQL_NTS, 0, 0, 0, 0);
SQLExecDirect(hstmt, (SQLCHAR*)"DELETE FROM Groups WHERE Id='S')", SQL_NTS);  
SQLINTEGER  rowCount = 0;
SQLRowCount(hstmt, &rowCount);
