I am using EDMX with MySql 5.1. It is working fine except When I try to execute the lambda expression, it shows me the following error :-
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '[XYZ].[UserID] AS [UserID], [XYZ].[FirstName] A' at line 17
where [XYZ] is the table name and [UserID], [FirstName] are the columns of that table. Following is the statement, that I want to execute -
_context.XYZSet.Where(org => org.ACDID == sbuID || !(org.ACDID.HasValue)).ToList();
Please help..
I do not know anything about EDMX, but from that error it looks like it's using MS SQL Server syntax to escape table and column names, which is not supported by MySQL. MySQL uses backticks for that, not square brackets.
If you could get EDMX to stop escaping the table and columns names then you might be okay, assuming none of the table/column names are reserved words.

create table 5390e910_abb3_40e2_bdfa_bd9d369e6dc6 like sample_table
is failing.
ERROR: #1064 - You have an error in your SQL syntax; check the manual

use near '5390e910_abb3_40e2_bdfa_bd9d369e6dc6 like

Now I don't see any flaw with the above name as the mysql documentation says:
64 characters max
can start with any alphabet/digit
an contain underscores/alphabets/digits
Though I am able to run something like this:
create table 1f8b784f_f580_4a82_9e93_167a2d9c79f5 like sample_table
I believe it's the first "e". When I swap that character for any other letter, the query works just fine.
I'm not positive on this, but my suspicion is that MySQL is reading your string and considering it to mean the number "5,390 times 10 to the power of 910abb3[etc]". And while all-numeric table names are valid they must be quoted.
Try enclosing your table name in back-ticks. This works for me:
create table `5390e910_abb3_40e2_bdfa_bd9d369e6dc6` like abbreviations;
Someone gave me this query to delete community from a database on my server using phpMyAdmin, it worked when he use it so I asked him to send it to me, but I get a error
MySQL said:
Documentation
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"SELECT * FROM `connections` WHERE 1" :
delete from connections where communit' at line 1
I did a search on the error but could not figure it out.
"SELECT * FROM `connections` WHERE 1" :
delete from connections where community="XYZ"
You should separate your queries with ; and not :
The error you are receiving as you've shown it is because this line is incorrect:
SELECT * FROM `connections` WHERE 1"
First because it's ending in an unnecessary double quotation mark. MySQL does not use double quotes but single quotes, and even still the other single quote is not there to match it.
The single quotes are also a problem for community="XYZ", this should read: community = 'XYZ'
Secondly, you don't have a condition for your where statement, you must be missing something like:
WHERE columnName = 1;
If you were trying to select everything from connections, you can just remove that where clause all together.
EDIT
In addition, MySQL queries are separated by a semi-colon, not a colon, so MySQL will not realize you are trying two different queries.
IF OBJECT_ID(N`db_291702_2`.`aaCoRrankingDateManage`, N'U') IS NOT NULL
BEGIN
PRINT 'Table Exists'
END
What is wrong with this? Why do I get errors?
Neither of the suggested ways in how-to-check-if-a-table-exists-in-sql-server/ works for me.
PS. "does not work" means errors like
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''db_291702_2'.'aaCoRrankingDateManage' LIMIT 0, 30' at line 1
Additional info:
I am using phpMyAdmin, my two databases are called db_291702_1 and db_291702_2, the latter has two tables, one of them is called aaCoRrankingDateManage
If you want to escape table or column names then use backticks
select `group` from table1
A static string must be included in quotes
select * from users where name = 'john'
And the syntax of every DB engine is a little bit different. The above works for MySQL, but SQL-Server has a different syntax. There you use brackets [] to escape names.
But you only need to escape names if you use reserved words. You don't have to escape everything.

I am using a portal system on my website and modified the ASP code heavily.
Since the website is growing, I want to migrate from MS Acces to MySQL.
Now, I think the portal I'm using (and some code I inputted) aren't MySQL compatable, because when I switch to the MySQL database, I get the following error.
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'

The SQL string regarding this line is the following:
Select [EzModuleID], [ModName] From EzCore_Plugin Where [IsModActive] = 1;
Im new to MySQL and I can't find why this is giving an error.
I've tried the quote's around 1, removing [], removing the space..
I think that when I figure out why this is causing an error, I can continue modifying the rest to make the website work on mysql.
Lose the square brackets
(I might as well post this as the answer rather than a comment)
In MySQL column and table names can be escaped with the backtick character ` or if the ANSI SQL mode is enabled with double quotes ".
Your WHERE clause (according to the error message) is Where IsModActive='1'. This works if IsModActive is a text column. If it is numeric, drop the single quotes. If IsModActive is a Boolean, change the clause to Where IsModActive IS true.
See: is operator
I have this bit of SQL that always returns an error, though I can't find why it is returning the error. I have connected to the database with no errors. I'm running PHP 5.2.17, MySQL 5.5.25a, and Apache 2.4.2.
The SQL:
DELETE FROM mail WHERE to=1
The error:
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near 'to=1' at line 1
TO is a reserved word, you need to use backticks:
DELETE FROM mail WHERE `to` = 1
By adding backticks on the column name escapes in from MySQL Reserved Word
DELETE FROM mail WHERE `to`=1
if the column to is not e.g. INT or DEC you should make it to = "1"
