![]() The point type is an example of a PostgreSQL-specific data type. The second example will store cities and their associated geographical location: Consequently, type names are not key words in the syntax, except where required to support special cases in the SQL standard. PostgreSQL can be customized with an arbitrary number of user-defined data types. PostgreSQL supports the standard SQL types int, smallint, real, double precision, char( N), varchar( N), date, time, timestamp, and interval, as well as other types of general utility and a rich set of geometric types. This might be convenient or confusing - you choose.) (Yes, the column of type date is also named date. real is a type for storing single precision floating-point numbers. Varchar(80) specifies a data type that can store arbitrary character strings up to 80 characters in length. From the Connections dialog, connect to a PostgreSQL Server. Otherwise it is created in the current schema. ) then the table is created in the specified schema. If a schema name is given (for example, CREATE TABLE myschema.mytable. ![]() The table will be owned by the user issuing the command. You can create other types of databases, including PostgreSQL databases. CREATE TABLE will create a new, initially empty table in the current database. ![]() SQL is case-insensitive about key words and identifiers, except when identifiers are double-quoted to preserve the case (not done above). How do I create a PostgreSQL database with Valentina Studio Out of the box, Valentina Studio creates two types of databases that do not require a server: ValentinaDB and SQLite. Whatever follows them is ignored up to the end of the line. That means you can type the command aligned differently than above, or even all on one line. White space (i.e., spaces, tabs, and newlines) can be used freely in SQL commands. psql will recognize that the command is not terminated until the semicolon. You can enter this into psql with the line breaks. You can create a new table by specifying the table name, along with all column names and their types:
