The maximal number of decimal digits in the resulting number; from 1 to 38.

The function is NULL-safe, meaning it treats NULLs as known values for comparing equality. Note that this is different from the EQUAL comparison operator ( = ), which treats NULLs as unknown values. See also: Wildcards in pattern include newline characters ( n) in subject as matches. LIKE pattern matching covers the entire string. To match a sequence anywhere within a string, start and end the pattern with %. NULL does not match NULL. In other words, if the subject is NULL and the pattern is NULL, that is not considered a match. TRY_TO_DATE. A special version of the TO_DATE function that performs the same operation (i.e. converts an input expression to a date), but with error-handling support (i.e. if the conversion cannot be performed, it returns a NULL value instead of raising an error).

Usage Notes. Using a single INSERT command, you can insert multiple rows into a table by specifying additional sets of values separated by commas in the VALUES clause. For example, the following clause would insert 3 rows in a 3-column table, with values 1, 2, and 3 in the first two rows and values 2, 3, and 4 in the third row: VALUES ( 1, 2, 3 ...

For syntax compatibility with other databases, Snowflake supports specifying non-default values for the constraint properties.

Wildcards in pattern include newline characters ( n) in subject as matches. LIKE pattern matching covers the entire string. To match a sequence anywhere within a string, start and end the pattern with %. NULL does not match NULL. In other words, if the subject is NULL and the pattern is NULL, that is not considered a match. In JSON, an object (also called a “dictionary” or a “hash”) is an unordered set of key-value pairs. TO_JSON and PARSE_JSON are (almost) converse or reciprocal functions. The PARSE_JSON function takes a string as input and returns a JSON-compatible VARIANT. The TO_JSON function takes a JSON-compatible VARIANT and returns a string. This is the substring that you want to replace. Typically, this is a literal, but it can be a column or expression. Note that this is not a “regular expression”; if you want to use regular expressions to search for a pattern, use the REGEXP_REPLACE function. replacement. This is the value used as a replacement for the pattern.The above df was created with column name “name” while the returned column name after collect() was called became “NAME”.
