Cause And Fixing Of SQL Server Syntax Error

SQL Syntax

Every programming language including SQL follows a specific set of guidelines, linguistic rules or patterns termed as Syntax. Each mathematical operators, special characters, spaces, etc., have a specific meaning when used in SQL query statements. For example, every SQL query or command must end with a semicolon (;).

Error SQL Syntax

SQL error message will appear on your screen, if you are executing a SQL command or query that does not have a proper format or syntax. Error SQL Syntax is the most common error experienced by the new SQL developers.

While working on query of database, there is a possibility of facing the database errors or SQL syntax errors. Here we explain about the SQL Server Error 1064 which may appear on your screen because of wrong SQL Syntax.

How to view SQL Syntax Errors

You can easily track down the errors in MS SQL by following below mentioned steps.

  • Open SQL Server Management Studio
  • Click on the View tab and then click on Error List

The Error List pane will show you all the errors found in SQL query.

Fix Error SQL Syntax

Causes of SQL Syntax Error

The Error SQL Syntax can have multiple causes. Some causes which can lead to a syntax error in SQL query are mentioned below.

Reserved Words

Each version of MS SQL has its own set of reserved words that performs specific set of function within in SQL engine. MS SQL Server will show you an error message when you attempt to use these reserved words as table name, filed name etc. For example, below is the SQL query that uses a reserved word "alter" as a table name,

Create TABLE alter (First _day date, last_day date);

How to fix Reserved Word Problem?

There is a special requirement to use a reserved word as a table or field name in SQL query. To run the SQL query having reserved word as table name, use a back ticks (`) just before and after that reserved word as shown below.

Create TABLE 'alter' (First _day date, last_day date);

Missing Data

Sometimes a missing data in the database can also lead a error SQL syntax issue when that data is needed for the SQL query. For example, if the database requires id number in integer for every student and a proper id is not given to a student. Such query can look like

Select * from students where student ID = $id

Since "$id" is not the proper integer, so for SQL Server ID is missing. For SQL server the query will look like this

Select * from students where student ID =

MS SQL engine will get confuse and show an error message when you execute the above mentioned command.

How to fix Missing Data issue?

Go into the respective database (within my admin), select the particular row from the table and then manually add the correct data.

Typing mistakes in commands

The most common cause for the SQL syntax error is mistyping of commands. For example, if you run the below mentioned command in MS SQL Server it will show you an SQL syntax error because UPDATE command is accidently misspelled.

UDPATE table1 SET id=2;

How to fix Error SQL Syntax?

Check your commands and ensures they are spelled correctly prior to executing them. Right syntax for the above mentioned command is

UPDATE table1 SET id=2;

Obsolete Commands

It is possible that some commands become obsolete and removed from SQL. You will see the SQL syntax error message when you use those commands in my SQL, because now those commands are not valid for SQL Statement. For example, TYPE command has been depreciated since MS SQL 4.1 and finally removed from version 5.1. Now the TYPE command has been replaced by the ENGINE command. You will get an error SQL syntax message if you will run the following command in new version of MS SQL.

Create Table STD (I int) TYPE = INNODB;

The TYPE command should be replaced by ENGINE.

Create Table STD (I int) ENGINE = INNODB;

Finding SQL syntax errors may be complicated; however the aforementioned Error list can help you to check errors while writing the projects and avoid searching of errors SQL syntax after writing the complete code. Sometimes the database can get corrupted due to such SQL Syntax errors or due to any other reason. In that case you can use SQL MDF recovery tool to fix error SQL syntax and view corrupted database of MS SQL Server.
