I'm looking for a way to do multiple row inserts when I'm only inserting data for a single column.
Here is the example table:
+-------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+-------------+------+-----+---------+----------------+
| id | tinyint(4) | NO | PRI | NULL | auto_increment |
| name | varchar(40) | NO | UNI | NULL | |
+-------+-------------+------+-----+---------+----------------+
I want to be able to insert something like ('admin', 'author', 'mod', 'user', 'guest') into the name column for each row.
The MySQL documentation shows that multiple inserts should be in the format:
INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);
However my statement ends up looking like this:
INSERT INTO User_Role(name) VALUES ('admin','author','mod','user','guest');
And I get the following:
ERROR 1136 (21S01): Column count doesn't match value count at row 1
Meaning that it thinks I'm trying to do a single row insert.
I'm not sure if I'm just missing something simple here, but I don't see anything in particular in the MySQL docs for this use case.
INSERT-SELECT-UNION query to insert multiple records Thus, we can use INSERT-SELECT-UNION query to insert data into multiple rows of the table. The SQL UNION query helps to select all the data that has been enclosed by the SELECT query through the INSERT statement.
INSERT INTO Syntax Specify both the column names and the values to be inserted: INSERT INTO table_name (column1, column2, column3, ...)
Insert multiple rows in MySQL with the help of “values”. You can enclose the values with parentheses set with comma separation.
INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of comma-separated column values, with lists enclosed within parentheses and separated by commas.
I will advise you Don't put multiple values in a column. make a new table:
INSERT INTO table_name (id, name) VALUES (1, 'name1'), (1, 'name2'), (1, 'name3'), (1, 'name4');
your syntax is a bit off. put parentheses around each data "set" (meaning a single value in this case) that you are trying to insert.
INSERT INTO User_Roll(name) VALUES ('admin'), ('author'), ('mod'), ('user'), ('guest');
