who is waiting to give you query??????? and "Post sample query." not even a request.

add auto_increment constraint to your primary key
try the below query to get next id

SQL

SELECT AUTO_INCREMENT FROM information_schema.TABLES
WHERE TABLE_SCHEMA =  'database_name'
AND TABLE_NAME =  'table_name';

Hi

SQL

CREATE TABLE TABLE_NAME
                (
                 COLUMN1 DATATYPE (OPTIONAL)PRIMARY KEY AUTOINCREMENT NOT NULL,
                 COLUMN2 DATATYPE (OPTIONAL)NULL,
                )

Example:

SQL

CREATE TABLE [ORDERS]
                (
                 [ORDER_ID] INTEGER  PRIMARY KEY AUTOINCREMENT NOT NULL,
                 [ORDER_BY] VARCHAR(50)  NULL,
                 [ORDER_DATE] TIMESTAMP  NULL,
                 [IS_ACTIVE] BOOLEAN  NULL
                )

This is the sample of create a table u can add as many columns as you can .
