![]() ![]() A binascii.Error exception is raised if s is incorrectly padded. Optional altchars must be a bytes-like object or ASCII string of length 2 which specifies the alternative alphabet used instead of the + and / characters. In the event of raw hex string, I use JavaScript’s parseInt() function to go from hex to decimal in an Uint8Array. Decode the Base64 encoded bytes-like object or ASCII string s and return the decoded bytes.Decoding the data is exactly the opposite of encoding. A Base64 encoded data is the one wherein the binary form of data is represented in printable ASCII string format by translating to radix-64 representation. After converting the characters to ASCII codes in an Uint8Array, zlib fails to decompress (with the default settings) gzip data: > import gzip > gzippeddata base64.b64encode(press(data)).decode() >. Base64 is a module in python that is used for encoding and decoding data. In the event of base64, window.atob() is used to decode the base64 encoded string first.Note: This example requires Chilkat v9.5.0. ![]() In all other cases it will assume a base64 encoding This example demonstrates how to decode, compress, and re-encode to smaller base64 representing the compressed data. ![]() It will first check for the 0x delimiter. The small JavaScript code in this Markdown file first determines what type of string it’s dealing with. Note that you have to right click and copy the cell to get the full length string copied to your OS’s clipboard For SSMS, you get the raw hex string with the 0x delimiter (e.g.Note that you have to export the query results to get the full length string copied to your OS’s clipboard. For the Azure Query Editor, you get the base64 string as a result (e.g.However, this depends on which program you’re using to view the model field in the dbo._MigrationHistory table. The EDMX is typically stored as a base64 string, which contains gzipped XML data. ![]() To make this all a bit easier, I’ve created a way to do this through some Javascript within this blog post. You’ll also have to copy and paste it over to a text editor and have an XML formatter installed to format it automatically, because you don’t want to do that manually.įinally, you still have the option to write a small script yourself that takes the copied value from either SSMS or the Azure Query editor and decompress it. There probably is some SQL command that decompresses it, but the result isn’t properly printed, as it would return a table. When you’re not connected to the database, all you have is the Azure Query editor or SQL Server Management Studio (SSMS). However, depending on the type of project your working on, this requires you to create a separate endpoint, IO process, or start a debug process to inspect the decompressed XML in a readable format.
