Wrapper for java.sql.Struct to emulate database structs, independently from the implementation.

1 Getting and setting attributes

Struct attributes are set on instance creation.

Copy

let struct = new Ax.sql.Struct('pie', 'jan',  10, 'feb',  20, 'march',  30, 'april',  40, 'may',  60, 'june',  60, 'july',  70, 'aug',  80, 'sept',  85, 'oct',  90, 'nov',  95, 'dec', 100);

Struct attributes can be retrieved with getAttributes(). As this function returns an Object[], we cannot simply print it. We have to iterate over its elements and print them.

Copy

let struct = new Ax.sql.Struct('vbar', 'jan',  10, 'feb',  20, 'march',  30, 'april',  40, 'may',  60, 'june',  60, 'july',  70, 'aug',  80, 'sept',  85, 'oct',  90, 'nov',  95, 'dec', 100);

for (elem of struct.getAttributes()) {
    console.log(elem);
}

2 Plot generation

This data structure can be used to generate plots in DBStudio.

Copy

var rows = [
    new Ax.sql.Struct('pie', 'jan',  10, 'feb',  20, 'march',  30, 'april',  40, 'may',  60, 'june',  60, 'july',  70, 'aug',  80, 'sept',  85, 'oct',  90, 'nov',  95, 'dec', 100),
    new Ax.sql.Struct('vbar', 'jan',  10, 'feb',  20, 'march',  30, 'april',  40, 'may',  60, 'june',  60, 'july',  70, 'aug',  80, 'sept',  85, 'oct',  90, 'nov',  95, 'dec', 100)
];

return  new Ax.rs.Reader().build(rows, options =>  options.setColumnNames(["col_struct"]));
