Create read update delete execute

In the following example, the multiple values are listed within in the parenthesis and each list is separated by a comma delimiter. The SQL select statement allows you to query the tables.

It allows you to retrieve specific data, one or more rows from one or more tables. Once you have column names, the table name is required in the FROM clause. So you separate each column with a comma, except, no comma after the last column. In this case, one that will return every row in the Address table. It provides a way to not have to list every column table s. The output lists all the columns of the Address table.

Naming conventions for CRUD procedures are often implemented differently from the naming conventions of other stored procedures. Some recommendations are as follows:.

The Create stored procedure inserts a new record into the table by using the Insert statement. Every column from the table has its own parameter:. This procedure reads the values from the table based on the primary key specified in the input parameter:.

This procedure updates the table based on the primary key that is specified in the Where clause:. This procedure deletes the records based on the primary key for a record specified in Where clause:. From the context menu under the Add submenu, choose the New Item command:. Right-click in the DataSet. This will open the TableAdapter Configuration Wizard window.

Insert: To perform insert operation using parameterized query we have to call insert function available in SQLiteDatabase class. It has total four parameters two are similar to insert function that is tableName and contentValues. Another two are whereClause String and whereArgs String[].

Similarly whereArgs array will contain values for those columns whose against? Update function will return number of rows affected if success, 0 otherwise. Here whereClause is optional, passing null will delete all rows in table. Important Note: If you want to remove all rows and require count of deleted ones also then pass 1 as whereClause.
