Partition Based on an Expression
Expression partitioning partitions a table by evaluating a SQL expression that you supply. For example, the
following statement partitions the table based on the month of the OrderDate column, using the MONTH function
as the SQL expression:
CREATE TABLE Orders
(
OrderId INT NOT NULL,
ItemId INT,
NumItems INT,
CustomerName VARCHAR(100),
OrderDate DATE,
Priority INT,
Status CHAR(10),
CONSTRAINT Pk_Orders PRIMARY KEY (OrderId)
)
PARTITION BY ( MONTH( OrderDate ) );
Colocating Related Rows from Multiple Tables
The COLOCATE WITH clause specifies the tables with which the partitioned table must be colocated.
Note: Tables that are referenced in the COLOCATE WITH clause must exist at the time you create the
partitioned table.
When two tables are partitioned on columns and colocated, it forces partitions having the same values for those
columns in both tables to be located on the same SQLFire member. For example, with range or list partitioning,
any rows that satisfy the range or list are colocated on the same member for all the colocated tables.
When you specify the COLOCATE WITH clause, you must use the PARTITION BY clause to specify partition
columns in the target tables in the same order using the same partitioning strategy (for example, with identical
ranges). The columns must also be of the same type, not considering constraints. Any REDUNDANCY or BUCKETS
clause must also be the same as the tables with which it is colocated.
Note: In order for two partitioned tables to be colocated, the SERVER GROUPS clauses in both CREATE
TABLE statements must be identical. In order for two replicated tables to be colocated, both tables must
specify the same server groups or one table's server groups must be a subset of the other table's server
groups.
For example, if you create the partitioned table, "countries," as follows:
CREATE TABLE COUNTRIES
(
COUNTRY VARCHAR(26) NOT NULL CONSTRAINT COUNTRIES_UNQ_NM Unique,
COUNTRY_ISO_CODE CHAR(2) NOT NULL CONSTRAINT COUNTRIES_PK PRIMARY KEY,
REGION VARCHAR(26),
CONSTRAINT COUNTRIES_UC
CHECK (country_ISO_code = upper(country_ISO_code) )
) PARTITION BY PRIMARY KEY
