![]() ![]() Note that, in this article, we have explained commonly used Teradata type conversion functions. To convert a String to INT uses sql conversion functions like cast or convert. SELECT type('123') as d_type įollowing are some of commonly used Teradata type conversion functions and examples on usage. expression expression is anything that will be converted. length It provides the length of the targettype. Similar to python, Teradata supports type function to verify the data type of an expression or column value.įor examples, consider below example to demonstrate typeof function to identify data type of an expression or value.Ĭonsider below example to identify the data type of ‘string’, you can use below syntax. Syntax : SELECT CONVERT ( targettype ( length ), expression ) Parameters: targettype Data type to which the expression will be converted, e.g: INT, BIT, SQLVARIANT, etc. Teradata Type Conversion Functionsīefore jumping into type conversion functions, let us see how to check the data type an expression or column value in Teradata. In short, you cannot run these functions without SELECT clause. SELECT CAST (CAST (MyVarcharCol AS NUMERIC (19,4)) AS INT) When copying data from TableA to TableB, the conversion is implicit, so you dont need the second convert (if you are happy rounding down to nearest INT): INSERT INTO TableB (MyIntCol) SELECT CAST. These conversion functions should be used within your Teradata SQL queries. To get around this just do two converts as follows: STRING -> NUMERIC -> INT. CAST ( expression AS datatype ( length ) ) CONVERT ( datatype (. is SAS format ('informat', to be exact) that tries to read in as many reasonable numeric formats as possible, it will work in. You need to replace yourstringvariable and yournewnumericvariable appropriately. Use the optional M and D parameters to specify the maximum number of digits (M) and the number of digits following the decimal point (D). To convert a String to INT uses sql conversion functions like cast or convert. Probably the best way would be to use: input (yourstringvariable, best.) as yournewnumericvariable. ![]() the first argument is the value to be formatted or converted, and the second argument is a template that defines the output or input format. Can be one of the following: Converts value to DATE. The type conversion functions use common calling function i.e. ![]()
