This statement is not populating the image_path column. I have copied and pasted column names from phpMyAdmin to ensure accuracy.
INSERT INTO (theme_name, theme_path, image_path)
VALUES ('',
'/Applications/MAMP/htdocs/waggleb/wp-content/plugins/app-switcher/themes/Original/',
'/Applications/MAMP/htdocs/waggleb/wp-content/plugins/app-switcher/thumbnails/original.png')
You're missing a table name. If you look at the MySQL INSERT syntax, you'll see that it's mandatory to include a table name.
As such, if you alter your query to become..
INSERT INTO <TABLE NAME> (theme_name, theme_path, image_path) VALUES...
...all should be well.
you missed the table name
INSERT INTO TABLENAME(theme_name, theme_path, image_path)
VALUES ('',
'/Applications/MAMP/htdocs/waggleb/wp-content/plugins/app-switcher/themes/Original/',
'/Applications/MAMP/htdocs/waggleb/wp-content/plugins/app-switcher/thumbnails/original.png')
I believe you are missing the table name.
It should be:
Insert Into [Table_name]
([Columns])
Values ([Values])
You've forgotten to name a table to INSERT into:
INSERT INTO my_table (theme_name, theme_path, image_path)
If you omitted the table name on purpopse, check that the datatypes are correct for the columns. Check lengths of target columns are long enough to hold what you are inserting.

I have the following problem:
I would't insert all the values in my db.
So, i would insert only id,tessera,nome,sex. I thought i had to write something like this:
INSERT INTO registries(id,tessera,'',nome,sex) VALUES (35983,35983,'DOG', 'FABIO', 'M')
I don't want to insert the DOG value in my db cause I don't have any attribute in my schema to save it.
I have 3000 rows and I take this row as example so I can't simply delete the DOG value and the attribute field in my sql query.
I remember that I have to use something like this
INSERT INTO registries(id,tessera,'',nome,sex)
I mean, I have to write '' to not consider the value in that position.
but MySQL gives me an error..
Can you help me?
You can handle this situation in following ways.
create temporary table on same server. Insert all data in temporary table then use insert into select statement and select required fields.
create temporary column and insert data in that column and delete temporary column
INSERT INTO registries (id,tessera,new_column,nome,sex)
VALUES (35983, 35983, '', 'FABIO', 'M');
Now
DROP COLUMN new_column from registries;
Try this (assuming dog is a column name):
INSERT INTO registries (id,tessera,dog_name,nome,sex) VALUES (35983, 35983, '', 'FABIO', 'M')
If dog_name is allowed to be NULL (which it is by default) you could also just not insert any value, like this:
INSERT INTO registries (id,tessera,nome,sex) VALUES (35983, 35983, 'FABIO', 'M')
I am trying to insert my values into table if Admin_User_Role_Id value against Admin_Id is not present in the table. Is it possible to insert!
My Table Structure:
Admin_User_Id (FK)
Admin_User_Role_Id (FK)
Is_Enabled (boolean flag)
Query which I tried, but not success
INSERT INTO role_association
SET Admin_User_Id=61, Admin_User_Role_Id=2, Is_Enabled=0
WHERE Admin_User_Role_Id
NOT IN
(SELECT Admin_User_Id, Admin_User_Role_Id FROM role_association)
I think it is possible but my logic is wrong. How should I manage this query to work successfully!
INSERT syntax cannot have WHERE clause. The only time you will find INSERT has WHERE clause is when you are using INSERT INTO...SELECT statement.
Probably you take care about where condition in your programming logic and write a simple insert statement and the depending on your logic use this statement to insert the records. Hope you got my point.
You want to insert your values in your table using this query for your reference
INSERT INTO Yourtablename(column1,column2,column3,...)
VALUES ('value1','value2','value3',.....);
You want to ADD one new column in your table means using this query
** ALTER TABLE table_name ADD column_name datatype**
For example i have table with a different field names(column), lets say 5 columns and all of them are empty. And i wanted to insert data in one specific column. Is it possible? I'm looking for example of this, but unlucky to find one. Most of insert into statements examples required all columns to be filled. If possible, can you give me the correct syntax? I'm sorry if i'm lacking research or it's already been asked, it's ok if you will redirect me to the link.
If you want insert on column3, leaving empty the other:
INSERT INTO table_name (column1,column2,column3,column4,column5)
VALUES ("","","VALUE","","");
The other part of program would UPDATE the other columns:
UPDATE table_name
SET column1=value1,column2=value2,column4=value4,column5=value5
WHERE some_column=some_value;
The documentation on how to construct an INSERT INTO statement is here: INSERT INTO Statement (Microsoft Access SQL).
But basically, you just need to be explicit about which columns you want to insert values for, and omit the other ones, like this:
INSERT INTO table (colname) VALUES ('colvalue')
What happens to the fields you omit? The documentation says:
When you do not specify each field, the default value or Null is inserted for missing columns.
I have a table named student which consists of (rollno, name, sem, branch)
If I want to INSERT only one value (i.e only name has to be entered) what is the query?
To insert values into specific columns, you first have to specify which columns you want to populate. The query would look like this:
INSERT INTO your_table_name (your_column_name)
VALUES (the_value);
To insert values into more than one column, separate the column names with a comma and insert the values in the same order you added the column names:
INSERT INTO your_table_name (your_column_name_01, your_column_name_02)
VALUES (the_value_01, the_value_02);
If you are unsure, have a look at W3Schools.com. They usually have explanations with examples.
insert into student(name) values("The name you wan to insert");
Be careful not to forget to insert the primary key.
First, if the table is all empty, just wanna make the column 'name' with values, it is easy to use INSERT INTO. https://www.w3schools.com/sql/sql_insert.asp.
`INSERT INTO TABLE_NAME (COLUMN_NAME) VALUES ("the values")`
Second, if the table is already with some values inside, and only wanna insert some values for one column, use UPDATE. https://www.w3schools.com/sql/sql_update.asp
UPDATE table_name SET column1 = value1 WHERE condition;
insert into student (name)
select 'some name'
or
insert into student (name)
values ('some name')
Following works if other columns accept null or do have default value:
INSERT INTO Student (name) VALUES('Jack');
Further details can be found from the Reference Manual:: 13.2.5 INSERT Syntax.
Execute this query, if you want the rest of columns as "#", do insert # inside the single quote which is left blank in query.
Also, there is no need of defining column name in the query.
insert into student values('','your name','','');
Thanks...
I normally found three ways of using MYSQL insert Command
INSERT INTO `table` (field1, field2, field3) VALUES ('value1', 'value2', 'value3');
or
INSERT INTO `table` VALUES ('value1', 'value2', 'value3');
or
INSERT INTO `table` SET `field1`='value1', `field2`='value2', `field3`='value3';
Is there any differences among these?
The first two are standard SQL; the third one is non-standard and specific to MySQL, derived from the standard syntax for UPDATE.
The difference between the first two is that one specifies the fields that you want to insert, which is more flexible because you can miss out fields if you're happy with them being set to NULL. Also specifying the fields means that the statement will still work if the table layout changes; if you don't specify the fields you're relying on the table never changing.
You are looking for differences in terms of what? In terms of usage, the first and third insert statements let you to set only those columns which you need whereas the second statement always tries to insert the values to all columns in order of table structure.
Only one difference, pretty obvious to me: the second one don't let you specify your own field set to insert.
