Learn all modern SQL in one place! SQL DECIMAL vs. It contains over 800 exercises and covers the basic, intermediate, and advanced topics of SQL.

If you're looking for a comprehensive SQL course, I recommend the interactive SQL from A to Z learning path. We’ve already posted a more general article on SQL data types this time, we’ll drill down further on just the DECIMAL and NUMERIC data types. Then I’ll discuss how these data types work in common SQL dialects. In this article, I’ll explain the differences and similarities between SQL’s standard NUMERIC and DECIMAL data types. However, in some variants of SQL, there is no difference! This article will clear up any confusion. There can be only column of this data type in the table.ĭata type for storing GUID (new by means of the NEWID function or existing from the string in the form xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, for example 6F9619FF-8B86-D011-B42D-00C04FC964FF).In standard SQL, there is a slight difference between the NUMERIC and DECIMAL data types. ODBC doesn't fully support this data type.įor storing the query result for the later usage.ĭata type generates automatically binary numbers, unique in the database, used usually to the rows identification. Unicode text string of variable length (maximum length: 2^30-1 = 1 073 741 823 characters)īinary data of fixed length (maximum length: 8000 bytes)īinary data of variable length (maximum length: 8000 bytes)īinary data of variable length (maximum length: 2^31-1 = 2 147 483 647 bytes)įor storing the reference to cursors in the variable or in a procedure (no in the CREATE TABLE method).įor storing value of another type (no text, ntext, image, timestamp, sql_variant) of max. Unicode text string of variable length (maximum length: 4000 characters) Unicode text string of fixed length (maximum length: 4000 characters) Text string of variable length (maximum length: 2^31-1 = 2 147 483 647 characters) Text string of variable length (maximum length: 8000 characters) Text string of fixed length (maximum length: 8000 characters) Values up to 29.998 are rounded down and values from 29.999 are rounded up to the nearest minute. 007.ĭata type representing date and time from to with the precision of 1 minute. Numeric data type with float precision that is defined as a float(24).ĭata type representing date and time from to with the precision about 3 ms. Numeric data type with float precision, where n is the number of mantis bits (1-24, precision of 7 digits, size of 4 bytes and 25-53, precision of 15 digits and size of 8 bytes).
