The update operation of SQLSet Pos makes the data source update one or more selected rows of a table, using data in the application buffers for each bound column (unless the value in the length/indicator buffer is SQL_COLUMN_IGNORE). To update rows with SQLSet Pos, the application does the following: #define UPDATE_ROW 100 #define DELETE_ROW 101 #define ADD_ROW 102 SQLUINTEGER Cust IDArray[11]; SQLCHAR Name Array[11][51], Address Array[11][51], Phone Array[11][11]; SQLINTEGER Cust IDInd Array[11], Name Len Or Ind Array[11], Address Len Or Ind Array[11], Phone Len Or Ind Array[11]; SQLUSMALLINT Row Status Array[10], Action, Row Num; SQLRETURN rc; SQLHSTMT hstmt; // Set the SQL_ATTR_ROW_BIND_TYPE statement attribute to use column-wise // binding.

Value); string str = "update testitem set [email protected], [email protected], [email protected] where [email protected] and [email protected]"; Sql Command cmd = new Sql Command(str, con); cmd. Note: Instead of using Text Box in normal mode use Labels. The following C# example reads the row for Adam Park Resort.SQLBind Col(hstmt, 1, SQL_C_ULONG, Cust IDArray, 0, Cust IDInd Array); SQLBind Col(hstmt, 2, SQL_C_CHAR, Name Array, sizeof(Name Array[0]), Name Len Or Ind Array); SQLBind Col(hstmt, 3, SQL_C_CHAR, Address Array, sizeof(Address Array[0]), Address Len Or Ind Array); SQLBind Col(hstmt, 4, SQL_C_CHAR, Phone Array, sizeof(Phone Array[0]), Phone Len Or Ind Array); // Execute a statement to retrieve rows from the Customers table.SQLExec Direct(hstmt, "SELECT Cust ID, Name, Address, Phone FROM Customers", SQL_NTS); // Fetch and display the first 10 rows.
