使用简单查询的SQL错误

Question

Im building an application but then learned we needed to use sql database and im getting this returned now and unsure why?

SQLSTATE[42000]: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Incorrect syntax near the keyword 'User'.

Query:

SELECT *
FROM User WHERE (username = 'james' OR email = 'james') AND password =
'M4erz2BE/N7NYyE40UJRo5W1E1ZiqKpOMWQhm+R8Esc='

Answer 1

Make sure you're querying the correct database and that the [User] table is defined in the default schema. Else you'll need to explicitly specify the schema before the table name.

Also when you use identifiers (Column, table or database names) adjust yourself to surrounding those with brackets. It makes the query more readable:

SELECT *
FROM [dbo].[User] WHERE ([username] = 'james' OR [email] = 'james') AND [password] =
'M4erz2BE/N7NYyE40UJRo5W1E1ZiqKpOMWQhm+R8Esc='

Answer 2

You are likely using the wrong database. Either specify the database name in your connection string, or fully qualify your table name.

Also, "User" is a reserved word . Change your query to this:

SELECT * FROM yourDatabaseName.dbo.[User] WHERE (username = 'james' OR email = 'james') AND password = 'M4erz2BE/N7NYyE40UJRo5W1E1ZiqKpOMWQhm+R8Esc='

Answer 3

Try this to select user, not sure but give it a try

      SELECT user 
      WHERE username = 'james' OR email = 'james'
      AND password ='M4erz2BE/N7NYyE40UJRo5W1E1ZiqKpOMWQhm+R8Esc='
