(Came up with this question in the course of trying to answer this other one)
Consider the following MS-SQL table, called GroupTable:
GroupID ------- 1 2 3
where GroupID is the primary key and is an Identity column.
How do you insert a new row into the table (and hence generate a new ID) without using IDENTITY_INSERT ON?
Note that this:
INSERT INTO GroupTable() Values () ... won't work.
edit: we're talking SQL 2005 or SQL 2008 here.
620
An explicit value for the identity column in table 'Students' can only be specified when a column list is used and IDENTITY_INSERT is ON. In simple words, the error says that since the flag IDENTITY_INSERT is off for the Id column, we cannot manually insert any values.
Yes. That's all you need to do. SET ON, write your code, SET OFF at the end.
INSERT INTO table(column1, column2,...) VALUES (value1, value2,...); To insert a row into a table, you need to specify three things: First, the table, which you want to insert a new row, in the INSERT INTO clause. Second, a comma-separated list of columns in the table surrounded by parentheses.
This should work:
INSERT INTO GroupTable DEFAULT VALUES Here you go:
INSERT INTO GroupTable DEFAULT VALUES If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
