describeTable(string $tableName, string $schemaName = null) : arrayReturns the column descriptions for a table.
The return value is an associative array keyed by the column name,
as returned by the RDBMS.
The value of each array element is an associative array
with the following keys:
SCHEMA_NAME => string; name of database or schema
TABLE_NAME => string;
COLUMN_NAME => string; column name
COLUMN_POSITION => number; ordinal position of column in table
DATA_TYPE => string; SQL datatype name of column
DEFAULT => string; default expression of column, null if none
NULLABLE => boolean; true if column can have nulls
LENGTH => number; length of CHAR/VARCHAR
SCALE => number; scale of NUMERIC/DECIMAL
PRECISION => number; precision of NUMERIC/DECIMAL
UNSIGNED => boolean; unsigned property of an integer type
PRIMARY => boolean; true if column is part of the primary key
PRIMARY_POSITION => integer; position of column in primary key
IDENTITY => integer; true if column is auto-generated with unique values
Parameters| Name | Type | Description |

| $tableName | string | |
| $schemaName | string | OPTIONAL |

- Todo
- Discover integer unsigned property.
lastInsertId(string $tableName = null, string $primaryKey = null) : stringGets the last ID generated automatically by an IDENTITY/AUTOINCREMENT column.
As a convention, on RDBMS brands that support sequences
(e.g. Oracle, PostgreSQL, DB2), this method forms the name of a sequence
from the arguments and returns the last id generated by that sequence.
On RDBMS brands that support IDENTITY/AUTOINCREMENT columns, this method
returns the last value generated for such a column, and the table name
argument is disregarded.
Parameters| Name | Type | Description |
|---|---|---|
| $tableName | string | OPTIONAL Name of table. |
| $primaryKey | string | OPTIONAL Name of primary key column. |
| Type | Description |
|---|---|
| string |
lastSequenceId(string $sequenceName) : stringReturn the most recent value from the specified sequence in the database.
This is supported only on RDBMS brands that support sequences
(e.g. Oracle, PostgreSQL, DB2). Other RDBMS brands return null.
Parameters| Name | Type | Description |

limit(string $sql, integer $count, integer $offset = 0) : stringAdds an adapter-specific LIMIT clause to the SELECT statement.
