I am not able to work with MySQL stored procedures in SSRS.
While using Mysql queries dataaset get created successfully. but if want to fetch data from stored procedures with parameter i get this error.
ERROR [42000] [MySQL][ODBC 8.0(a) Driver][mysqld-8.0.13]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 'ims_data.GetUploadStatus' at line 1
ODBC does not support named parameters. you need to use ? for parameters
You can try
CALL ims_data.GetUploadStatus(?)
or
EXEC ('CALL ims_data.GetUploadStatus(?)', #p_period) AT MySQL (Linked Server Name)

I'm running MySQL 8.0.26 inside a Linux container, using Docker.
I am attempting to run a stress test by infinitely selecting data from a table named employees in the employees database. To attempt this, I am embedding a SELECT statement inside of a WHILE loop, with a search condition that always returns true.
I am attempting to issue the following query against the MySQL engine, using the MySQL CLI tool.
WHILE 1=1 DO
SELECT * FROM employees.employees;
END WHILE;
When I run this query, I receive the error message as follows.
Error invoking remote method 'DB_EXECUTE_CANCELLABLE_QUERY': 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 'WHILE 1=1 DO SELECT * FROM employees.employees; END WHILE' at line 1
According to the MySQL documentation, I am using the correct syntax. What is wrong with this SQL statement?
Docs: MySQL Comparison Operators
Docs: MySQL WHILE Statement
The WHILE statement is only valid inside MySQL stored procedures, functions.
I want to use my SQL'book_data2' file from the desktop E drive as a 'SOURCE'. But I am getting an error code 1064 in MySQL workbench. Could you help me for that issue? I am giving the code and action output below.
Code:
SOURCE E:\DataPractice\Practice\book_data2.sql;
Action Output:
Error Code: 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 'SOURCE E:\DataPractice\Practice\book_data2.sql' at
line 1 0.000 sec
There are a number of commands that are supported by the mysql client (that is, the command-line client, not MySQL Workbench), but they are parsed in the client, not sent to the server as SQL statements. The MySQL Server does not recognize these commands.
It can be confusing, but remember both the client and the server may process commands. You just have to read the documentation to learn which commands are in the list of client-only commands:
https://dev.mysql.com/doc/refman/8.0/en/mysql-commands.html
(Except USE, which is recognized by both mysql client and server, just to make sure there's an exception to every rule!)
If you want to use MySQL Workbench to "source" an SQL file, in other words load a file, read the SQL commands in that file, and execute them, Workbench does support this action, but they call it Data Import/Restore. It's documented here: https://dev.mysql.com/doc/workbench/en/wb-admin-export-import-management.html
I want to execute SOURCE data/keyw.sql from C program. This query works fine when I execute from the command line but gives the following error on executing mysql_query(con, "SOURCE data/keyw.sql")
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 'SOURCE data/keyw.sql' at line 1
Any help would be highly appreciated.
The SOURCE command is not executed on the MySQL server. It is interpreted by the mysql Client, and is basically just a convenience.
Quote from MySQL documentation:
mysql sends each SQL statement that you issue to the server to be executed. There is also a set of commands that mysql itself interprets. For a list of these commands, type help or \h at the mysql> prompt:
Note that source is one of those listed. If you want to know how it works, then have a look at the source code for the mysql Client.
If your source to be executed contains more than one MySQL statement then your connection will need to support multiple statement execution, or alternatively you need to parse the SQL into individual statements yourself.
I am using RMySQL to connect and manipulate MySQL.
Now I have a SQL like:
"drop table if exists t_tmp; create table t_tmp(name varchar(20));"
which works just fine in MySQL CLI.
But when I put these SQLs to RMySQL.dbExecute() exception throws:
"could not run statement: 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 'create table t_tmp(name varchar(20))' at line 1"
I am trying to run the 2 SQLs respectively, then they both work out OK.
Is there any way I can put the whole STRING(SQLs) and run it correctly in RMySQL?
Thanks!
I'm trying to parameterize a set of frequently used queries in my workbench.
This works:
select * from providers where id='112233';
This
WbVarDef var1=112233;
select * from providers where id='$[var1]';
gives error
Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'from providers where id='112233'' at line 1
My reference was this.
Just to be clear, these are in the MySQL workbench and not a workbench script file or a mysql script file.
In MySQL, syntax for setting variable is below.
SET #var1 = '112233';
and using the variable would be as below.
select * from providers where id=#var1;

Based on your tag mysql-workbench, I find it simply to be a case where the referenced documentation and use is not relevant to what you are using.
Back up the hierarchy from your link to this http://www.sql-workbench.net/
