![]() ![]() Each column not present in the target list will be inserted using a default value, either its declared default value or null. The SQL INSERT statement, sometimes referred to as INSERT INTO, is how we go about inserting new records into a table in our database. The columns in the target list may be listed in any order. One can insert a single row at a time or several rows as a result of a query. Use LIMIT to specify top 20 rows, but I think you need to sort them using ORDER BY clause first. To insert values in particular columns, use the following syntax: INSERT INTO table (col2,col3) VALUES (val2,val3) Code language: PostgreSQL SQL dialect and PL/pgSQL (pgsql) Let’s say the first column is of type serial id, therefore we will not need to insert a value for that column. INSERT allows one to insert new rows into a table. I don't like that nested dblink, but AFAIK I can't reference to tblB in dblink_exec body. ![]() If my understanding is correct (postgres has tbla and dbtest has tblb and you want remote insert with local select, not remote select with local insert as above): psql dbtest Call the addBatch() method of the PreparedStatement. How to insert values into a table from a select query in PostgreSQL Asked 12 years, 1 month ago Modified 1 year, 4 months ago Viewed 845k times 376 I have a table items (itemid serial, name varchar (10), itemgroup int) and a table itemsver (id serial, itemid int, name varchar (10), itemgroup int). I just saw your revised question (closed as duplicate, or just very similar to this). Inserting multiple rows into a table Create a database connection. You can make it as prepared statement if you want and it works as well: PREPARE migrate_data (integer) AS PostgreSQL has record pseudo-type (only for function's argument or result type), which allows you query data from another (unknown) table. INSERT INTO tblB (time) VALUES (5000), (2000) ĬREATE TABLE tblA (id serial, time integer) įROM dblink('dbname=dbtest', 'SELECT id, time FROM tblB') ![]() For example: psql dbtestĬREATE TABLE tblB (id serial, time integer) If you create the table like above, You can use default in following way to insert: INSERT INTO Participant values (default) Check out SQLFIDDLE. You can insert rows specified by value expressions, zero, or multiple rows resulting from the query. As Henrik wrote you can use dblink to connect remote database and fetch result. In PostgreSQL, the insert statement helps insert a new row or row into the table. ![]()
