Parameters:

Region (string) – Specified only if the base tables belong to a different Amazon Web Services Region.
CatalogId (string) –
[REQUIRED]

The ID of the Data Catalog where the partitions in question reside. If none is provided, the AWS account ID is used by default.
DatabaseName (string) –
[REQUIRED]

The name of the catalog database where the partitions reside.
TableName (string) –
[REQUIRED]

The name of the table that contains the partition.
Expression (string) –
An expression that filters the partitions to be returned.

The expression uses SQL syntax similar to the SQL WHERE filter clause. The SQL statement parser JSQLParser parses the expression.

Operators: The following are the operators that you can use in the Expression API call:

=

Checks whether the values of the two operands are equal; if yes, then the condition becomes true.

Example: Assume ‘variable a’ holds 10 and ‘variable b’ holds 20.

(a = b) is not true.

< >

Checks whether the values of two operands are equal; if the values are not equal, then the condition becomes true.

Example: (a < > b) is true.

>

Checks whether the value of the left operand is greater than the value of the right operand; if yes, then the condition becomes true.

Example: (a > b) is not true.

<

Checks whether the value of the left operand is less than the value of the right operand; if yes, then the condition becomes true.

Example: (a < b) is true.

>=

Checks whether the value of the left operand is greater than or equal to the value of the right operand; if yes, then the condition becomes true.

Example: (a >= b) is not true.

<=

Checks whether the value of the left operand is less than or equal to the value of the right operand; if yes, then the condition becomes true.

Example: (a <= b) is true.

AND, OR, IN, BETWEEN, LIKE, NOT, IS NULL

Logical operators.
