PostgreSQL doesn’t know how to automatically cast input of type text to input of type equipment. You have to explicitly declare your strings as being of type equipment: ARRAY[‘projector’,’PAsystem’,’safe’]::equipment[] I confirmed this with SQL Fiddle.
Here is what i ended up doing. I hope it helps someone. INSERT INTO persons (firstname,lastname) VALUES (‘John’,’Doe’); SET @person_id = LAST_INSERT_ID(); INSERT IGNORE INTO properties (property) VALUES (‘property_A’); SET @property_id = LAST_INSERT_ID(); INSERT INTO has_property (person_id,property_id) VALUES(@person_id, @property_id); INSERT IGNORE INTO properties (property) VALUES (‘property_B’); SET @property_id = LAST_INSERT_ID(); INSERT INTO has_property (person_id,property_id) VALUES(@person_id, … Read more
Choose SQL Insert extractor in the drop-down menu. Them you’ll be able to copy (Ctrl/Cmd+C) data as a bunch of INSERTS. Or use Export button next to the extractor.
The column names do not matter at all, as long as data types match (or can be cast in the assignment). If the data types of the columns don’t match, try casting the values accordingly. Just try with small dummy tables. Be sure to list the target columns explicitly to avoid confusion. Like this: INSERT … Read more
If you define the columns with double quotes, then you generally need to use them when you refer to the column: insert into tester3 (“UN0”, “UN1”) values ( 1, ‘jishnu1′); I would suggest you remove the double quotes from the column names in the CREATE TABLE statement. You don’t need the double quotes if the … Read more
Please try below code to insert values in tables using for loop. do $$ begin for r in 1..1000 loop insert into schema_name.table_name(id) values(r); end loop; end; $$;
To populate the column during insert, use a DEFAULT value: CREATE TABLE users ( id serial not null, firstname varchar(100), middlename varchar(100), lastname varchar(100), email varchar(200), timestamp timestamp default current_timestamp ) Note that the value for that column can explicitly be overwritten by supplying a value in the INSERT statement. If you want to prevent … Read more
You may use AddWithValue method like: string connString = ConfigurationManager.ConnectionStrings[“default”].ConnectionString; MySqlConnection conn = new MySqlConnection(connString); conn.Open(); MySqlCommand comm = conn.CreateCommand(); comm.CommandText = “INSERT INTO room(person,address) VALUES(@person, @address)”; comm.Parameters.AddWithValue(“@person”, “Myname”); comm.Parameters.AddWithValue(“@address”, “Myaddress”); comm.ExecuteNonQuery(); conn.Close(); OR Try with ? instead of @, like: string connString = ConfigurationManager.ConnectionStrings[“default”].ConnectionString; MySqlConnection conn = new MySqlConnection(connString); conn.Open(); MySqlCommand comm = conn.CreateCommand(); … Read more
In CRUD operations, the INSERT is the ‘C’ and the UPDATEis the ‘U’. They are two of the four basic functions of persistent storage. The other two are SELECT and DELETE. Without at least these four operations, a typical database system cannot be considered complete. Use INSERT to insert a new record. Use UPDATE to … Read more
You aren’t inserting a value for id. Since you don’t explicitly set it, it’s implicitly given a null value, which is, of course, not a valid value for a primary key column. You can avoid this entire situation by defining this column as serial instead of a plain old integer, and leave all the heavy … Read more
