by

Introduction

This question is related to the System.Data.SqlClient.SqlException error which occurs when there is an incorrect syntax near the value ‘9988’. This error can be caused by a variety of issues, such as incorrect SQL syntax, incorrect data types, or incorrect values being passed to the database. In this article, we will discuss the possible causes of this error and how to resolve it. We will also provide some tips on how to prevent this error from occurring in the future.

Solution

The issue is likely caused by a syntax error in the SQL query. Check the query for any typos or incorrect syntax. It is possible that the query is trying to use a reserved keyword as an identifier, or that the query is missing a closing quotation mark.


There must be a problem in one of your input parameters those you are directly reading from controls.

This is not recommended anyway due to SQL injection attack threat.

If you change your queries to us parameters (parameter queries), I hope this issue will be resolved.

Following is an example how to use parameters. Note that I am not using your code in example:

SqlCommand objSqlCommand = null;
strSQL = @"INSERT INTO ... (Field1, ...)
                    VALUES 
                    (@param1, ...)";
objSqlCommand = new SqlCommand(strSQL);
objSqlCommand.Parameters.Clear();
objSqlCommand.Parameters.AddWithValue("@param1", yourControl.Text);
....
....
objSqlCommand.ExecuteNonQuery();
objSqlCommand.Dispose();

You should further improve this code by including using block or proper try/catch blocks.

This way, if there is any SQL query sensitive character in your input, it will be handled correctly and issue will be resolved. This is also strongly recommended to save yourself from SQL Injection Attack.

When working with databases, it is important to be aware of the potential for errors. One such error is the System.Data.SqlClient.SqlException: Incorrect syntax near ‘9988’ error. This error occurs when the syntax of a SQL query is incorrect, usually due to a typo or incorrect formatting.

The first step in resolving this error is to identify the exact query that is causing the issue. This can be done by examining the SQL query in the error message. Once the query has been identified, it can be checked for any typos or incorrect formatting. If any typos or incorrect formatting is found, it should be corrected and the query should be re-run.

If the query is correct, then the issue may be due to incorrect data types. For example, if the query is expecting an integer value, but the data type of the value is a string, then the query will fail. In this case, the data type of the value should be changed to match the expected data type.

Finally, if the query is still failing, then the issue may be due to incorrect permissions. If the user running the query does not have the correct permissions to access the data, then the query will fail. In this case, the user should be granted the necessary permissions to access the data.

In summary, the System.Data.SqlClient.SqlException: Incorrect syntax near ‘9988’ error occurs when the syntax of a SQL query is incorrect. To resolve this issue, the query should be checked for typos or incorrect formatting, the data type of the value should be checked, and the user should be granted the necessary permissions to access the data.
