MIDB

The MIDB function outputs the (left) N bytes specified by the Count property starting from the Xth byte specified by the Offset property.

Input/Output

Number of Connections: Min: 1/Max:3

Input	Data Type	Description
Input1	Binary	The data.
Input2	Integer	Sets the Offset property. (optional)
Input3	Integer	Sets the Count property. (optional)

Output	Data Type	Description
Output1	Binary	The selected data.

Property

Name	Property Type	Description
Offset	int	The offset, in bytes, from the start of the input data from which byte data is selected. The first byte in the input data is "1".
Count	int	The number of bytes to select.

Topic

• A value less than 1 entered in the Offset property will result in an error. The mapper component that this function is in will abort and throw an exception.
• A negative Count value results in the bytes to the left of the Offset being selected.
• If the value entered in the Count property is 0, or the Offset is greater than the number of bytes in the input data, zero bytes of data will be output.
• If the Offset + Count is greater than the number of bytes, all the bytes from the Offset to the end of the byte stream will be output.

How a Binary function handles byte conversions

The Binary Functions LEFTB, RIGHTB, MIDB, REPLACEB and TRUNCATEB handle input binary data as it is. If binary data cannot be successfully converted back to a string, an empty string is output.

Example

		Property		Output
Input1	0x6165696F75	Offset	2	0x6569
		Count	2
