Grabbing JSON, manipulating and extracting arrays from it etc. But what about the inverse, going from a JSON array to rows?

mysql convert string to json

For example, say I have a JSON array and want to insert a row for each element in the array with its value? The trick is to perform a join on a temporary or inline table of indexes, which gives you a row for each non-null value in a JSON array. You need as many numbers in the index table as the max length of any array in your JSON data.

It's a bit of a hack, and it's about as painful as the OP's example, but it's very handy. Good: Clear, short, easy code, no need to know array size, no loop, no invoke other function will be fast. I was working in a report where there was a big json array list in one column.

For doing this process, I had to use a while in a stored procedure since I do not know the maximum size:. Learn more. Asked 3 years, 6 months ago. Active 2 months ago. Viewed 37k times. And my heart.

I had assumed that table valued functions were supported, since pretty much every other DBMS under the sun has them. Apparently MySQL's the odd man out on that. Ahh, MySQL MySQL has no array-like data structure other than tables. The JSON functions should not be considered blanket license to denormalize your schema.

Well, if there were table valued functions like other DBMS have, then it would be a table returned, not some other array-like structure Active Oldest Votes. Example requires MySQL 5.

I currently have a MySQL table that contains a column to store category ids. These ids are stored in a JSON string. I am looking for the most efficient method to query these JSON string for a specific id. Any other ideas would be much appreciated.

Should work. MySQL 5. If you really need to query specific values in your JSON string you are much better off to try and store the individual values in the database. In the example above you could just create a field table that joins to the posts table.

Then a simple join statement will get you all of the right values. Learn more.

Thus, it is important that we take note of the supported data types. Figure 1. Figure 2. The results of the above scripts are shown in below in which a single array represented by square bracket was returned with rows held as objects represented by curly braces. Figure 5. Figure 6 shows the revised script with a join to another fictitious customer lookup dimension that stores additional information regarding customers that have purchased fruits.

The execution of the above script results into an output that is shown in Figure 7. You will now notice that another child array with its own objects labelled cust appears in the output. The child array represents the information retrieved from the customer dimension. Figure 7. However, when we change the column order of the SELECT statement such that it begins with a column from the customer dimension as shown in Figure 8we get a different output than the one in Figure 7 in that the child array is now based off the FruitSales dimension.

Figure 9. In fact, all columns from the two tables are shown in the same root level.

Figure To organise the JSON output into child arrays, you will have to use the dot syntax as shown in Figure The label before the dot represents the name of the object — in this case we have two objects named Sales and Cust. Figure 16 shows the application of the ROOT option. You will notice that the last four values in my dummy transaction are NULL. There are instances whereby you want the square brackets excluded from the output because you may want to concatenate two or more JSON data.
