First, we will create a table that has primary key. Next, we will drop the primary key successfully using the correct syntax of SQL Server.
CREATE TABLE Table1(
Col1 INT NOT NULL,
Col2 VARCHAR(100)
CONSTRAINT PK_Table1_Col1 PRIMARY KEY CLUSTERED (
Col1 ASC)
)
GO
Second, try to drop the primary key constraint using following lines.
/* For SQL Server/Oracle/MS ACCESS */
ALTER TABLE Table1
DROP CONSTRAINT PK_Table1_Col1
GO
/* For MySql */
ALTER TABLE Table1
DROP PRIMARY KEY
GO
Use the tips!!!
