Conversion function Description
Array split Decomposes the data in an array column into individual elements and registers them in individual columns.
The name of each column after decomposition is automatically set by default.

[Target column]
INT8/INT16/INT32/INT64 array
UINT8/UINT16/UINT32/UINT64 array
BOOLEAN/FLOAT/DOUBLE array
Bit Conversion Converts bitN through bitM of the column data to integers and registers them in the column.
For an integer scalar, bitN through bitM of the integer are treated as is.
For a Boolean array, each element [N] through [M] of the array is treated as bitN through bitM.
For INT8/UINT8 type arrays, each element, which has 8 bits, is converted to bit with 0 or !0, and each element [N] through [M] are treated as bitN through bitM.


[Target column]
Integer scalar
BOOLEAN type array
INT8/UINT8 type array (where each element is treated as 0 or 1)
Change Data Name Registers the input data as is as separate data with a set name in a column.
