It is possible for the query ( SELECT statement) to also contain a WITH clause. The WITH clause allows you to specify one or more subqueries that can be referenced by name in the INSERT query. If you use the query clause to insert rows from a query, you of course need to have SELECT privilege on any table or column used in the query.

Use of the RETURNING clause requires SELECT privilege on all columns mentioned in RETURNING.

However, ON CONFLICT DO UPDATE also requires SELECT privilege on any column whose values are read in the ON CONFLICT DO UPDATE expressions or condition. Similarly, when ON CONFLICT DO UPDATE is specified, you only need UPDATE privilege on the column(s) that are listed to be updated.

If a column list is specified, you only need INSERT privilege on the listed columns. If ON CONFLICT DO UPDATE is present, UPDATE privilege on the table is also required. You must have INSERT privilege on a table in order to insert into it. WHERE clause condition was not satisfied, the row will not be returned. For example, if a row was locked but not updated because an ON CONFLICT DO UPDATE. Only rows that were successfully inserted or updated will be returned. The syntax of the RETURNING list is identical to that of the output list of SELECT. However, any expression using the table's columns is allowed.

This is primarily useful for obtaining values that were supplied by defaults, such as a serial sequence number. The optional RETURNING clause causes INSERT to compute and return value(s) based on each row actually inserted (or updated, if an ON CONFLICT DO UPDATE clause was used). ON CONFLICT can be used to specify an alternative action to raising a unique constraint or exclusion constraint violation error. Tables with unique indexes might block if concurrent sessions perform actions that lock or modify rows matching the unique index values being inserted the details are covered in Section 64.5. INSERT into tables that lack unique indexes will not be blocked by concurrent activity. If the expression for any column is not of the correct data type, automatic type conversion will be attempted. The values supplied by the VALUES clause or query are associated with the explicit or implicit column list left-to-right.Įach column not present in the explicit or implicit column list will be filled with a default value, either its declared default value or null if there is none. If no list of column names is given at all, the default is all the columns of the table in their declared order or the first N column names, if there are only N columns supplied by the VALUES clause or query. The target column names can be listed in any order. One can insert one or more rows specified by value expressions, or zero or more rows resulting from a query. async function addToDB(event, brandDetails), else it will consider as a string in array.INSERT inserts new rows into a table.

I got stuck and confused about how to proceed. I thought of using: INSERT INTO beautiful (name, age) Again if 'Samia' is not present, the row should be inserted. 'name' above, should be checked and if such a 'name' already exists, the corresponding whole row should be updated otherwise inserted.įor instance, in the example below, if 'Katrina' is already present in the database, the whole row, irrespective of the number of fields, should be updated. The problem is when I execute this query, I want to check whether a UNIQUE key (which is not the PRIMARY KEY), e.g. so I used something like: $sql = "INSERT INTO beautiful (name, age) I have a SQL query where I want to insert multiple rows in single query.
