BINARY_TO_BITMAP

binary_to_bitmap(binary)

Description

The main function of binary_to_bitmap is to convert input data of binary type into bitmap type. This function is usually used in conjunction with the bitmap_to_binary function, which converts bitmap type to binary type. This conversion is very useful when dealing with bitmap data, especially in scenarios where conversion between different data formats is needed.

Parameter Description

• binary: The binary type data to be converted.

Return Result

Returns the converted bitmap type data.

Example

1. Create a bitmap array using the bitmap_build function, convert it to binary type using the bitmap_to_binary function, and finally restore it to bitmap type using the binary_to_bitmap function:

SELECT binary_to_bitmap(bitmap_to_binary(bitmap_build(array(1,2,3))));
-- [1,2,3]

Precautions

• Ensure that the input binary data is valid; otherwise, the function may not execute correctly.
• In practical applications, you may need to combine other bitmap functions to achieve more complex operations. Make sure to understand the usage of related functions before using the binary_to_bitmap function.

Through the above examples and explanations, you can better understand the purpose and usage of the binary_to_bitmap function. When dealing with bitmap data, this function can help you easily convert between different data formats, thereby improving data processing efficiency.
