Updating pl sql

Set the SQL_ATTR_ROW_STATUS_PTR statement // attribute to point to the row status array.SQLSet Stmt Attr(hstmt, SQL_ATTR_CURSOR_TYPE, SQL_CURSOR_KEYSET_DRIVEN, 0); SQLSet Stmt Attr(hstmt, SQL_ATTR_ROW_BIND_TYPE, SQL_BIND_BY_COLUMN, 0); SQLSet Stmt Attr(hstmt, SQL_ATTR_ROW_ARRAY_SIZE, 10, 0); SQLSet Stmt Attr(hstmt, SQL_ATTR_ROW_STATUS_PTR, Row Status Array, 0); // Bind arrays to the Cust ID, Name, Address, and Phone columns.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.

PL/SQL is able to take advantage of this behavior and perform short-circuit evaluations allowing it to stop evaluating logical expressions once the final result can be determined.A trigger is a pl/sql block structure which is fired when a DML statements like Insert, Delete, Update is executed on a database table.A trigger is triggered automatically when an associated DML statement is executed.We can create a trigger to update the 'product_price_history' table when the price of the product is updated in the 'product' table.1) Create the 'product' table and 'product_price_history' table Once the above update query is executed, the trigger fires and updates the 'product_price_history' table.The performance improvements associated with accessing rows directly using rowids rather than primary key searches will be covered next.Using rowids when updating Rowids are Oracle's internal row-level identifiers and are used during index creation to provide the link between index keys and the rows they point to.rc = SQLFetch Scroll(hstmt, SQL_FETCH_NEXT, 0); Display Data(Cust IDArray, Cust IDInd Array, Name Array, Name Len Or Ind Array, Address Array, Address Len Or Ind Array, Phone Array, Phone Len Or Ind Array, Row Status Array); // Call Get Action to get an action and a row number from the user.while (Get Action(&Action, &Row Num)) // Close the cursor.The rowid_script shown below gives an example of this.The script creates a test table as a copy of the all_objects view and then loops through the table twice updating each row at a time.
