To answer this question, we need to understand the different return codes in SQL and their meanings.

Return code -180 in SQL typically indicates an "Invalid date or time" error. This error occurs when there is an issue with the format or value of a date or time value being used in a SQL statement.

Let's go through each option to understand why it is correct or incorrect:

Option A) Foreign Key constraint - This option is incorrect because return code -180 does not indicate a foreign key constraint error. Foreign key constraint errors are usually indicated by different return codes, such as -530 or -532.

Option B) Bind Issue - This option is incorrect because return code -180 does not indicate a bind issue. Bind issues are typically indicated by different return codes, such as -803 or -805.

Option C) Invalid date or Time - This option is correct because return code -180 does indicate an "Invalid date or time" error. This error occurs when there is an issue with the format or value of a date or time value being used in a SQL statement.

Option D) Invalid string - This option is incorrect because return code -180 does not indicate an invalid string error. Invalid string errors are typically indicated by different return codes, such as -305 or -432.

The correct answer is C) Invalid date or Time. This option is correct because return code -180 is associated with an "Invalid date or time" error.

To answer this question, we need to understand the possible meanings of SQL return code -811.

SQL return code -811 typically indicates that a SELECT statement returned more than one row. Therefore, option B, "Fetching more than one row," is the correct answer.

Let's go through each option to understand why it is correct or incorrect:

A) Fetching only Zero Rows - This option is incorrect because SQL return code -811 does not indicate that zero rows were fetched. It specifically indicates that more than one row was fetched.

B) Fetching more than one row - This option is correct. SQL return code -811 indicates that a SELECT statement returned more than one row.

C) Table not found - This option is incorrect. SQL return code -811 is not related to a table not being found. It specifically indicates that multiple rows were fetched.

D) BOTH A and B - This option is incorrect. SQL return code -811 does not indicate fetching zero rows. It specifically indicates fetching more than one row.

Therefore, the correct answer is B) Fetching more than one row because SQL return code -811 indicates that a SELECT statement returned more than one row.

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Dead Lock - This option is incorrect because a dead lock is a situation where two or more transactions are permanently blocked, waiting for each other to release the resources they need to continue executing. It is not related to return code -922 in SQL.

Option B) Time Out - This option is incorrect because a timeout occurs when a process or query takes longer than a specified time to complete. It is not related to return code -922 in SQL.

Option C) BOTH A and D - This option is incorrect because option A (Dead Lock) is incorrect. Therefore, it cannot be both A and D.

Option D) Authorization failure - This option is correct because return code -922 in SQL typically indicates an authorization failure. It means that the user does not have the necessary permissions or privileges to perform the requested operation.

The correct answer is D. This option is correct because return code -922 in SQL indicates an authorization failure.
