The number of rows backward from the current row from which to obtain a value. For example, an offset of 2 returns the expr value with an interval of 2 rows.

When using the TRIM (including LTRIM and RTRIM) function, the leading and trailing tabs or other non-space white characters are not removed.

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.The hidden culprit here is the presence of NULL values in the column referenced in the subquery. We need to note that NULL value will always be part of the output returned by the Distinct clause. So even if we have one NULL value in the column which is referenced in the subquery for the NOT IN clause the entire WHERE clause will …

The phone number can be NULL for a region. Insert values into the table: The following SELECT statement uses the NVL function to retrieve the phone_region_1 and phone_region_2 values. This example shows the following results for the NVL function: The IF_REGION_1_NULL column contains the value in phone_region_1 or, if that value is NULL, the ...If {IGNORE | RESPECT} NULLS is not specified, the default is RESPECT NULLS (i.e. a NULL value will be returned if the expression contains a NULL value and it is the first value in the expression).

The reason for this is tied to the convoluted history of SQL, and it has been well argued whether or not this is a good feature or not. Regardless, it's what we have.Constraints other than NOT NULL are created as disabled. Snowflake enforces only NOT NULL. You can create NOT NULL constraint while creating tables in the cloud database. A Snowflake table can have multiple NOT NULL columns. Snowflake NOT NULL Constraint Syntax. There are many methods that you can use to add NOT NULL on Snowflake table.To specify more than one string, enclose the list of strings in parentheses and use commas to separate each value, e.g. NULL_IF ('NULL', 'NUL', ''). Note that NULL_IF can include empty strings and only applies to columns that are nullable. When unloading data, Snowflake converts SQL NULL values to the first value in the list.

Elements that are not extracted¶ Elements with the following characteristics are not extracted into a column: Elements that contain even a single “null” value are not extracted into a column. You can trivially determine which columns may or may not contain null values by querying the COLUMNS view of INFORMATION_SCHEMA: select COLUMN_NAME, IS_NULLABLE from YOUR_DB.INFORMATION_SCHEMA.COLUMNS. where TABLE_NAME = 'YOUR_TABLE_NAME' and TABLE_SCHEMA = 'PUBLIC'; However, this won't tell you whether these columns actually ever contain null.Watch out for snowflakes too.
