I'm having a problem trying to do an INSERT, it's succeeding even though it shouldn't.
My table structure:
Note: given1, given2 and given3 are required fields.
In my application I execute the following method (https://github.com/catfan/Medoo):
$this->medoo->insert('teste', ['dado2' => 11, 'dado3' => 'teste']);
This should not be accepted because data2 is of type SET, and data3 is of type INTEGER`. Even so, the insertion succeeds. Moreover, data1 is not passed as an argument, even though it is a required field.
I checked the MySQL log and got the following entries:
SET SQL_MODE=ANSI_QUOTES;
INSERT INTO "teste" ("dado2", "dado3") VALUES ('11', 'teste');
Running this SQL manually in the database, I discovered that the problem is in using ANSI_QUOTES. The database somehow accepts the insert, and instead of issuing an error message it issues a warning:
I think that is need to modify the Medoo source code or report this problem to MySQL. I do not know what to do.
MySQL version is 5.7.14
I use the MySQL Workbench 6.3.6
When mySQL server is set in STRICT mode, it produces error when you try to insert values that do not fit into a column. By calling SET SQL_MODE=ANSI_QUOTES; this strict mode is most likely disabled.
You can try to contact the author of Medoo framework or rather use another framework or just PDO to access your database.
See mysql docs on server modes for more information.

I am working with an old SQL database and have many errors when trying to insert a new data record via PDO:
Field 'field_name' doesn't have a default value
As I can see, the old PHP code in this project uses old mysql_ functions and ignores such circumstances.
The database is old and large, and I don't know if I can change the column settings in the tables without unexpected consequences. So I want add values for all these columns in my însert-request.
How can I get the list of all the SQL fields in the particular table that have no default value?
PS. I have added my SQL request as an answer, but are there possibly other options or other important considerations for my situation?
For MariaDB this SQL request works well:
SELECT i.COLUMN_NAME, i.COLUMN_TYPE, i.COLUMN_DEFAULT, i.IS_NULLABLE
FROM information_schema.columns i
WHERE
i.TABLE_SCHEMA = 'my_database_name'
AND i.TABLE_NAME = 'my_table_name'
AND i.COLUMN_DEFAULT IS NULL
When doing an INSERT via PHP into a MSSQL DB, I get the following error:
mssql_query(): message: Cannot insert the value NULL into column
'wmu_startdate', table 'wmuPortal.dbo.tbl_projects'; column does not
allow nulls. INSERT fails. (severity 16)
But the SQL string is
INSERT INTO tbl_projects
(startdate)
VALUES
(
(SELECT CAST('31-08-2016' as datetime))
)
The Query executes fine when run in Microsoft SQL Server Management Studio. Via the PHP Extension, the error above occurs. I already toggled mssql.datetimeconvert = Off #/On in php.ini.
The same error occurs without the SELECT CAST statement, ie. only a String as the value. The startdate column is of type datetime.
UPDATE
I now have a working query. But this still doesn't solve whatever causes the incorrect handling of dates by default...
Replacing the SELECT CAST Statement with
(SELECT CONVERT(DATETIME, '31-08-2016', 105))
Does the trick. Now: What setting do I have to alter in order to get the mssql/freetds extension to handle this automatically?
A known-good test server does not specify anything in /etc/freetds/locales.conf or other places. mssql.datetimeconvert = Off is set on both servers.
I also set other time/date related options in php.ini (copied from known-good server), without success. Is datetime handling affected by other system/environment variables?
I'm designing a web interface for my clients database (A .mdb MS Access file). I'm using an ODBC driver to connect to it and the odbc_ functions provided by PHP.
My problem is access's 'append' queries. From what I gather, it's just inserting more rows, but something is breaking the query from executing:
INSERT INTO test ( TITLE, [LEVEL], UNITID, TITLEM, COHORTPLUSOPTIONS )
SELECT \"OPTION ONLY\" AS Expr, Units.LEVEL, UnitOptionNumbers.ID, Units.TITLE,
UnitOptionNumbers.OPTIONCOHORT
FROM UnitOptionNumbers INNER JOIN Units ON UnitOptionNumbers.ID = Units.ID WHERE
(((UnitOptionNumbers.NOAWARD)=Yes));
The most helpful error message I can get is:
[ODBC Microsoft Access Driver] Too few parameters. Expected 1.
Which isn't helpful at all. I'm confident with mySQL, but I just cannot pinpoint the problem here. Please can you help me find the reason the query wont execute, or help me figure out a work around.
Thanks for your time.
I don't have enough reputation to comment but perhaps it could be a problem with the fact that your table "test" has two fields with the same name ("TITLE")
According to Microsoft:
"This error occurs only with Microsoft Access when one of the column names specified in a select statement does not exist in the table being queried."
The solution therefore is to change
SELECT \"OPTION ONLY\" AS Expr
to
SELECT 'OPTION ONLY'
It seems the original code attempted to fill the first field with a default text value I.e "OPTION ONLY". "OPTION ONLY" was being read as a column name it seems.
I am using a readymade script to backup my MySQL database using PHP. I store the resultant query in a variable.
If I echo the variable, and copy paste the output into the MySQL console, it works perfectly.
But when I run the same using 'mysql_query' (I know it is depreciated, kindly ignore that), I get the dreaded Syntax error.
Here's the echo output (first 2 lines) :
INSERT INTO assign
VALUES('75085','rsam','CE0001/CZ0001/CPE183/CSC183','1','1','3.0','13','1','1','13','2','10.00','117.00','0','0');INSERT
INTO assign
VALUES('75086','rsam','CE0001/CZ0001/CPE183/CSC183','1','2','3.0','13','1','1','13','2','10.00','97.50','0','0');
And here's the exact 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 'INSERT INTO assign
VALUES('75085','rsam','CE0001/CZ0001/CPE183/CSC183','1','1'' at line 1
If anyone can point out what I am obviously missing, I would be grateful!
As the documentation for mysql_query() says:
mysql_query() sends a unique query (multiple queries are not supported) to the currently active database on the server that's associated with the specified link_identifier.
You might be interested in mysql_multi_query():
Executes one or multiple queries which are concatenated by a semicolon.
While mysql_query is limited to a single statement, this situation can be avoided as multiple records can be inserted into the same table with only one statement:
INSERT INTO assign (...)
VALUES(...),
VALUES(...);
This will save on round-trip latency (over multiple mysql_query) which might matter.
See Inserting multiple rows in mysql
Okay, so I'm currently using mysqli_real_escape_string to escape my SQL queries before sending them to MySQL via PHP. Yet, for some reason my queries aren't processing, and when I outputted the MySQL query and pasted it in to PHPMyAdmin, it gave the following error:
#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 'WHERE ind={A$RTkAIqah0J1N$Fqymnud9s5PwnWw2wC.Y02oDo4H3W8QJPoJ$6$KK8UearuUCDH$FQg' at line 1
Now, the following is my query:
INSERT INTO `db`.table(`colheader`) VALUES ('{\"hey\":[\"Hello world\",\"7\\/9\\/2013\"]}') WHERE ind='$6$RTkAIqah0J1N$Fqymnud9s5PwnWw2wC.Y02oDo4H3W8QJPoJ$6$KK8UearuUCDH$FQgSnLHIlkBOtDTzu9AuZIZTr6GS4Rzr.iW11041994'
Now, I know that the string assigned to 'ind' has some issues, but I tried putting a slash before every period and every dollar sign and it still doesn't work. I tried putting the whole thing in double quotes, even brackets. Nothing. Could anyone point out what I'm clearly missing? I've looked at the documentation and can't seem to find anything. Thank you in advance!!
WHERE serves to filter which records will be affected or retrieved by your query, and INSERT servers to append a whole new record to a table.
An INSERT can never affect existing records, therefore its nonsense to have a WHERE clause. INSERT does not support WHERE.
If you are trying to edit the value of a field on an existing record, use UPDATE instead.
Take a look at the MySQL Reference Manual for details about its usage.
if your trying to make an update to the specified index use
UPDATE `db`.table SET `colheader` = '{\"hey\":[\"Hello world\",\"7\\/9\\/2013\"]}' WHERE ind='$6$RTkAIqah0J1N$Fqymnud9s5PwnWw2wC.Y02oDo4H3W8QJPoJ$6$KK8UearuUCDH$FQgSnLHIlkBOtDTzu9AuZIZTr6GS4Rzr.iW11041994'
