Examples The following examples convert numbers, timestamps, and dates to strings. You can cast, the number to a string/text, and then parse that string, or do some integer math, and use date_from_part I believe the later will perform better over larger datasets. Type casting with Snowflake CAST.
Convert any data type easily in Snowflake-we've got you covered on how to do it, tips, examples and its limitations. In order to customize format numbers with comma separation in Snowflake result set, fields with a number data type first need to be converted to a string, by casting to varchar or char data type. There is an optional SQL format model parameter in number-to-string conversion functions to specify how to format numbers when converting to a string.
To convert a number to text, we use TO_VARCHAR. Snowflake CAST and TRY_CAST: Converting Data Types In Snowflake, the CAST function and: operator convert data from one type to another, ensuring that data fits the required format for operations or consistency in databases. In Snowflake, SQL format models (i.e.
literals containing format strings) are used to specify how numeric values are converted to text strings and vice versa. As such, they can be specified as arguments in the TO_CHAR, TO_VARCHAR and TO_DECIMAL, TO_NUMBER, TO_NUMERIC conversion functions. Collation specifications aren't retained when values to are cast to text string data types (for example, VARCHAR and STRING).
You can include collation specifications when you cast values (for example, CAST (myvalueASVARCHAR)COLLATE'en-ai'). When you use the: alternative syntax, you cannot specify the RENAMEFIELDS or ADDFIELDS arguments. The output shows that the TM9 text-minimal format element prints precisely the number of digits in the fractional part based on the specified scale.
For more information, see Text-minimal numeric formats. Convert a number that uses a comma to separate groups of digits. Date format specifier for string_expr or AUTO, which specifies that Snowflake automatically detects the format to use.
For more information, see Date and time formats in conversion functions. The default is the current value of the DATE_INPUT_FORMAT session parameter (default AUTO). Type conversions: how to and implications Working with a database often makes it necessary to perform type conversions.
