+# sql-simple-parser
+sql ddl parser to support extensions for drawio
+
+## Getting started
+* how to use:
+```typescript
+import {SqlSimpleParser} from "@funktechno/sqlsimpleparser"
+
+var sample = `CREATE TABLE "humanresources_department" (
+	"departmentid" serial NOT NULL,
+	"name" Name NOT NULL,
+	"groupname" Name NOT NULL,
+	"modifieddate" timestamp NOT NULL,
+	PRIMARY KEY("departmentid")
+);`
+
+// run parser
+const parser = new SqlSimpleParser('postgres')
+
+// get models
+const models = parser
+  .feed(sql)
+  .ToModel();
+```
+* outputs
+```json
+{
+	"TableList": [
+		{
+			"Name": "humanresources_department",
+			"Properties": [
+				{
+					"Name": "departmentid",
+					"ColumnProperties": "serial NOT NULL",
+					"TableName": "humanresources_department",
+					"ForeignKey": [],
+					"IsForeignKey": false,
+					"IsPrimaryKey": true
+				},
+				{
