Run the following INSERT command to insert a record into the technicians table where 0 is used for the Boolean value. The 0 is not acceptable for the Boolean value in PostgreSQL. So, an error message will appear. # INSERT INTO technicians VALUES (2, 'Kabir Hossain', 0); The following output will appear after executing the above insert query. PostgreSQL supports a single Boolean data type: BOOLEAN that can have three values: true , false and NULL . PostgreSQL uses one byte for storing a boolean value in the database. The BOOLEAN can be abbreviated as BOOL. In this syntax: First, specify the name of the table ( table_name) that you want to insert data after the INSERT INTO keywords and a list of comma-separated columns ( colum1, column2, .... ). Second, supply a list of comma-separated values in a parentheses (value1, value2, ...) after the VALUES keyword. Example 3: how do you insert boolean to postgresql.

So, an error message will appear. # INSERT INTO technicians VALUES (2, 'Kabir Hossain', 0); The following output will appear after executing the above insert query. In the above command, the inserted value length is six into the Name column. And the value is still inserted into the column. However, the PostgreSQL cuts the trailing space before adding the value. We can check it with the following command's help, where the Insert command is added successfully.. They provide a TINYINT data type instead of Boolean or Bool data types.

If you want to accept 0 and 1 as boolean, your best bet is probably to create the table with the column defined as smallint with a CHECK (colname >= 0 AND colname <= 1) condition.. After import you can ALTER TABLE to change the type to boolean and provide a USING term to do the type conversion.. Alternately, use a more flexible data-loader, like pgloader, Pentaho Kettle,.
