SnowConvert AI - Vertica - Predicates¶

ALL & ANY array expressions¶

Description¶

An expression used to evaluate and compare each element of an array against a specified expression. (Vertica Language Reference ANY & ALL (array))

Grammar Syntax¶

expression operator ANY (array expression)
expression operator ALL (array expression)

To support this expression SnowConvert AI translates the <> ALL to NOT IN and the = ANY to IN

Sample Source Patterns¶

Input Code:¶

SELECT some_column <> ALL (ARRAY[1, 2, 3]) 
FROM some_table;

SELECT *
FROM someTable
WHERE column_name = ANY (ARRAY[1, 2, 3]);

Output Code:¶

SELECT some_column NOT IN (1, 2, 3)
FROM some_table;

SELECT *
 FROM someTable
 WHERE column_name IN (1, 2, 3);

Known Issues¶

There are no known issues

LIKE¶

LIKE Predicate

Description¶

Retrieves rows where a string expression—typically a column—matches the specified pattern or, if qualified by ANY or ALL, set of patterns (Vertica SQL Language Reference Like Predicate)

Grammar Syntax¶

 string-expression [ NOT ] { LIKE | ILIKE | LIKEB | ILIKEB }
   { pattern | { ANY | SOME | ALL } ( pattern,... ) } [ ESCAPE 'char' ]

Vertica Substitute symbols¶


Symbol	Vertica Equivalent	Snowflake Equivalent
~~	LIKE	LIKE
~#	LIKEB	LIKE
~~*	ILIKE	ILIKE
~#*	ILIKEB	ILIKE
!~~	NOT LIKE	NOT LIKE
!~#	NOT LIKEB	NOT LIKE
!~~*	NOT ILIKE	NOT ILIKE
!~#*	NOT ILIKEB	NOT ILIKE

In Vertica, the default escape character is the backslash (\). Snowflake doesn’t have a default escape character. SnowConvert AI will automatically add the ESCAPE clause when needed.

It’s important to know that Snowflake requires the backslash to be escaped (\\) when you use it as an escape character within both the expression and the ESCAPE clause. This means you’ll need two backslashes to represent a single literal backslash escape character in Snowflake queries. SnowConvert AI handles this by automatically escaping the backslash for you.

Sample Source Patterns¶

Success

This syntax is fully supported in Snowflake.

Vertica¶

 SELECT path_name
FROM file_paths
WHERE path_name ~~ '/report/sales_2025_q_.csv';

-- Find a path containing the literal '50%'
SELECT path_name
FROM file_paths
WHERE path_name LIKE '%50\%%';

-- Find a path starting with 'C:\'
SELECT path_name
FROM file_paths
WHERE path_name ILIKEB 'C:\\%' ESCAPE'\';

Snowflake¶

SELECT path_name
FROM file_paths
WHERE path_name LIKE '/report/sales_2025_q_.csv';

-- Find a path containing the literal '50%'
SELECT path_name
FROM file_paths
WHERE path_name LIKE '%50\\%%' ESCAPE'\\';

-- Find a path starting with 'C:\'
SELECT path_name
FROM file_paths
WHERE path_name ILIKE 'C:\\\\%' ESCAPE'\\';

Known Issues¶

While SnowConvert AI handles most backslash patterns, some complex expressions may still cause query failures. We recommend reviewing complex patterns to prevent these issues.
