SQL Error: ORA-00933: SQL command not properly ended

Question

I am trying to update a record in oracle SQL developer by using Joins. Following is my query-

UPDATE system_info set field_value = 'NewValue' 
FROM system_users users 
JOIN system_info info ON users.role_type = info.field_desc 
where users.user_name = 'uname'

However, when I tried to execute it, I got following error-

Error report: SQL Error: ORA-00933: SQL command not properly ended 
              00933. 00000 - "SQL command not properly ended"

I tried removing JOINS

UPDATE system_info info 
SET info.field_value = 'NewValue' 
FROM system_users users 
where users.user_name = 'uname' AND users.role_type = info.field_desc

but still having same error can anybody tell me the error reason and solution

Answer 1

Semicolon ; on the end of command had caused the same error on me.

cmd.CommandText = "INSERT INTO U_USERS_TABLE (USERNAME, PASSWORD, FIRSTNAME, LASTNAME) VALUES ("
                + "'" + txtUsername.Text + "',"
                + "'" + txtPassword.Text + "',"
                + "'" + txtFirstname.Text + "',"
                + "'" + txtLastname.Text + "');"; <== Semicolon in "" is the cause.
                                                      Removing it will be fine.

Hope it helps.

Oracle does not allow joining tables in an UPDATE statement. You need to rewrite your statement with a co-related sub-select

Something like this:

UPDATE system_info
SET field_value = 'NewValue' 
WHERE field_desc IN (SELECT role_type 
                     FROM system_users 
                     WHERE user_name = 'uname')

For a complete description on the (valid) syntax of the UPDATE statement, please read the manual:

Answer 3

Your query should look like

UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value

Answer 4

Not exactly the case of actual context of this question, but this exception can be reproduced by the next query:

update users set dismissal_reason='he can't and don't want' where userid=123

Single quotes in words can't and don't broke the string. In case string have only one inside quote e.g. 'he don't want' oracle throws more relevant quoted string not properly terminated error, but in case of two SQL command not properly ended is thrown.

Summary: check your query for double single quotes.

Answer 5

its very true on oracle as well as sql is "users" is a reserved words just change it , it will serve u the best if u like change it to this

UPDATE system_info set field_value = 'NewValue' 

FROM system_users users JOIN system_info info ON users.role_type = info.field_desc where users.user_name = 'uname'
