用于获取所有内部逗号的正则表达式

Question

我有这个json文件：

{
sql: "CREATE TABLE EXAMPLE    ID INT PRIMARY KEY     NOT NULL,
'NAME'           TEXT    NOT NULL,
'AGE'            INT     NOT NULL,
'ADDRESS'        CHAR(50),
'SALARY'         REAL",
}

我需要在带有正则表达式的JSON文件中获取列名和列类型，但我是正则表达式中的菜鸟。

所有程序都在js。

Answer 1

const obj = {
  sql: `CREATE TABLE EXAMPLE    ID INT PRIMARY KEY     NOT NULL,
'NAME'           TEXT    NOT NULL,
'AGE'            INT     NOT NULL,
'ADDRESS'        CHAR(50),
'SALARY'         REAL`,
};
const regex = /'(.*)'\s*(\S*)/g;
let m;

while ((m = regex.exec(obj.sql)) !== null) {
  // This is necessary to avoid infinite loops with zero-width matches
  if (m.index === regex.lastIndex) {
    regex.lastIndex++;
  }

  // The result can be accessed through the `m`-variable.
  m.forEach((match, groupIndex) => {
    console.log(`Found match, group ${groupIndex}: ${match}`);
  });
}
