I try to "alter Table" I need one more AI field, not key... "List" ID INT(11):PK Not Null AutoIn.. Name VARCHAR UserID INT(11):FK Not Null edit BOOL and now i need one more field "sortpos" as AI. I try it with MySQL Workbench ALTER TABLE `**mydb**`.`List` ADD COLUMN `sortpos` INT(11) NOT NULL AUTO_INCREMENT AFTER `edit`; Can u help me? Thx You can't get better error message than this one. You already have ID defined as Auto Increment in your table. Now you are trying to add another field sortpos as auto increment which is not allowed. One table can only have one auto increment which must be

I'm trying to add a column to an MS Access database table using pyodbc and Python 3.5. Using the expression self.cursor.execute("ALTER TABLE data ADD COLUMN testColumn TEXT(10)") works fine, but when I try to add a default value (DEFAULT "no"), it throws a Syntax error. I've tried multiple combinations, but no luck. Any help is much appreciated! Cheers Sadly, the Access ODBC driver simply does not support the DEFAULT clause for a column in CREATE/ALTER TABLE statements. The ODBC driver and OLEDB provider for Access have diverged somewhat in their DDL support, so unfortunately we can get

ALTER TABLE tada_prod . action_6_weekly ADD COLUMN id INT NULL AUTO_INCREMENT UNIQUE AFTER member_id ; works, so i thought, to add the column as the first column i could do ALTER TABLE `tada_prod`.`action_6_weekly` ADD COLUMN `id` INT NULL AUTO_INCREMENT UNIQUE BEFORE `code`; but i get a syntax error, what is the correct syntax? ALTER TABLE `tada_prod`.`action_6_weekly` ADD COLUMN `id` INT NULL AUTO_INCREMENT UNIQUE FIRST; php You can add column only after particular field or at first not before. The mysql query for add column after particular filed is: ALTER TABLE table_name ADD COLUMN column

I am having some problems with a query because of errors in the code that I did not create. $query = $this->db->query("ALTER TABLE `" . DB_PREFIX . "customer` ADD `customer_type` TINYINT(1) NOT NULL; I'm not a coder, but have so far fixed (I think) the error. By comparing with other queries that don't throw errors and reading quite a few similar posts on stackoverflow, I added a missing quote, a parenthese, and semi-colon. No more error, but not sure if this is even the correct way of doing it? I ended up with this: $query = $this->db->query("ALTER TABLE `" . DB_PREFIX . "customer` ADD

Hello The following procedure will have to move all constraints from one table to the other however I am having some difficulties at the point where the constraint should be deleted. The problem: how do I use variables in the following line ALTER TABLE var_referenced_table_name DROP FOREIGN KEY var_constraint_name; when I use as is, I receive the following error Error Code: 1146. Table 'oaf_businesslink_dev.var_referenced_table_name' doesn't exist MySQL does not recognise var_referenced_table_name and var_constraint_name as variables. DELIMITER // DROP PROCEDURE IF EXISTS AlterConstraints//

I have existing table which has 10 years of data (I have taken dump). I would like to Range partition the existing table on one date key column within the table. Most of the examples I see are with CREATE TABLE..PARTITION BY RANGE... to add new partitions. But my table is existing table. I assume I need some ALTER statement. ALTER TABLE TABLE_NAME PARTITION BY RANGE(CREATED_DATE) PARTITION JAN16 VALUES LESS THAN (01-02-2016), PARTITION FEB16 VALUES LESS THAN (01-03-2016) AND GREATER THAN(31-01-2016),//OR? PARTITION MAR16 VALUES BETWEEN (01-03-2016) AND (31-03-2016), //OR? Two questions.. Do I

I'm using SQLite, which doesn't support adding a constraint to an existing table. So I can't do something like this (just as an example): ALTER TABLE [Customer] ADD CONSTRAINT specify_either_phone_or_email CHECK (([Phone] IS NOT NULL) OR ([Email] IS NOT NULL)); Are there any workarounds for this scenario? I know: I can add a constraint for a new table, but it isn't new (and it's generated by my ORM, EF Core) I can do a "table rebuild" (rename table, create new one, copy old data, drop temp table) but that seems really complex Ideas Can I somehow make a copy of the table into a new table, with
