If you come from the SQL Server world you might be wary of the Text data type. A Boolean data type can hold one of three possible values: true, false or null. Oracle to SQL Server Bit String Types are used to store bit masks. PostgreSQL supports character data types for storing text values. For example, the `timestamp` data type in SQL Server isn't at all what you'd think, and `text` is an old deprecated type with poor performance. Other than this, arrays play an important role in PostgreSQL. PostgreSQL specialists suggest to replace such values by NULLs while migrating data from MySQL. It can convert hundreds or thousands of tables in one go. Writing code in comment? data type for case-insensitive character strings: cube: 1.4: data type for multidimensional cubes: dblink: 1.2: connect to other PostgreSQL databases from within a database: dict_int: 1.0: text search dictionary template for integers: dict_xsyn: 1.0: text search dictionary template for extended synonym processing: earthdistance: 1.1 Unfortunately, pg 12 raised some errors of its own. XML type: This XML data type in PostgreSQL allows users to store XML data in data types, in the form of extensions. Example 1: SQL Server 1. varchar(n):variable-length with limit 2. char(n):fixed-length, blank padded 3. text, varchar:variable unlimited length To test YugabyteDB’s support for character types, let’s create a table that has columns with these types specified: Next, let’s load data into the table: The insert above should succeed. It is represented as varchar(n) in PostgreSQL, where n represents the limit of the length of the characters. Sybase ASE to Oracle The CHAR is fixed-length character type while the VARCHAR and TEXT are varying length character types. PostgreSQL builds character data types off of the same internal structures. It adds extensions to text data types. The following query illustrates the idea: The value of n must be a positive integer for these types. All Rights Reserved. Double precision values are treated as floating point values in PostgreSQL. So I think there's some good high-level advice here that applies across multiple flavors, but the specifics are really only applicable to PostgreSQL. … In the rest of the document, we have discussed each of the PostgreSQL Data Types based on PostgreSQL 9.1 Version.

Sybase ASE to MySQL The text data type is basically used to store the unlimited length of the variable, we can store unlimited variable length into the column field using text data type in PostgreSQL. This data type is used to store characters of limited length. Another challenge while mapping types is to remember that unlike PostgreSQL, MySQL allows to store '0000-00-00' into date columns. This type supports full text search, which is the activity of searching through a collection of natural-language documents to locate those that best match a query. PostgreSQL text is used to define the text data type for the column, varchar, and text data type is the character data type in PostgreSQL. However, the character length limit the VARCHAR function places on data permits for faster access than the TEXT data type. Data type restrictions. There are different categories of data types in PostgreSQL. Table 8-4 shows the general-purpose character types available in PostgreSQL.. SQL defines two primary character types: character varying(n) and character(n), where n is a positive integer. In the rest of the document, we have discussed each of the PostgreSQL Data Types based on PostgreSQL 9.1 Version. The PostgreSQL database offers an interesting advantage of working with compound types because of its simple and efficient way of converting values to a particular data type in an SQL query. We dug into the postgres code and found a limit in the config with a comment dating it to the pg 8.5 era. PostgreSQL supports CHAR, VARCHAR, and TEXT data types. Sybase ASE to PostgreSQL MySQL to SQL Server, IBM DB2 to MySQL It provides definitions for both as well as 5 examples of how they can be used and tips and tricks.
