我正在将SQL Server的存储过程转换为PostgreSQL中的存储函数。我将存储过程转换为函数。转换后，我在pgadmin中运行了该脚本，但是如果条件接近，它将给出语法错误。
存储的功能：
<html>
<head>
<script>
function addRow() {
var table = document.getElementById("bod");
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
row.insertCell(0).innerHTML = '<input type="text" name="purpose_dy[]" class = "uname" id="purpose" size="20" onkeyup="success()"/>';
row.insertCell(1).innerHTML = '<input type="text" name="wafernum_dy[]" class = "wafernum" id="wafernum" size="20" onkeyup="success()"/>';
row.insertCell(2).innerHTML = '<input type="text" name="cell_dy[]" class = "cell" id="cell" size="20" onkeyup="success()"/>';
row.insertCell(3).innerHTML = '<input type="text" name="qty_dy[]" class = "qty" id="qty" size="20" onkeyup="success()"/>';
row.insertCell(4).innerHTML = '<input type="text" name="remarks_dy[]" class = "remarks" id="remarks" size="20" onkeyup="success()"/>';
row.insertCell(5).innerHTML = '<input type="button" value="Delete" onClick="Javacsript:deleteRow(this)"/>';
}
function success() {
// get all the elements present in form
var unameArray = document.getElementsByClassName("uname");
var ageArray = document.getElementsByClassName("age");
var cellArray = document.getElementsByClassName("cell");
var qtyArray = document.getElementsByClassName("qty");
var wafernumArray = document.getElementsByClassName("wafernum");
var purposeArray = document.getElementsByClassName("purpose");
var remarksArray = document.getElementsByClassName("remarks");
// Check for number of tr
var rowCount = document.getElementById("bod").rows.length;
for(var i=0;i<rowCount;i++) {
var uname = unameArray[i];
var age = ageArray[i];
var cell = cellArray[i];
var qty = qtyArray[i];
var wafernum = wafernumArray[i];
var purpose = purposeArray[i];
var remarks = remarksArray[i];
if (uname === "" || age === "" || cell === "" || qty === "" || wafernum === "" || purpose === "" || remarks === "") {
document.getElementById('submit_form').disabled = true;
document.getElementById('submit_form').style.backgroundColor = "initial";
break;
} else {
document.getElementById('submit_form').disabled = false;
document.getElementById('submit_form').style.backgroundColor = "yellow";
}
}
}
</script>
<style>
</style>
</head>
<body>
Name: <input type="text" id="uname" /> Age: <input type="text" id="age" />

<input type="submit" name="submit" id="submit_form" value="Submit" onclick="SaveData()" disabled>
</body>
</html>错误：
在条件附近显示语法错误。我在下面添加了错误代码：
CREATE OR REPLACE FUNCTION getuserdepartmentlist(p_nUserID bigInt,p_sRole varchar(100),p_nInstID bigInt = 0) RETURNS TEXT

此代码可以正常工作，没有错误。上面的代码中的游标声明是错误的。
CREATE OR REPLACE FUNCTION getuserdepartmentlist(p_nUserID bigInt,p_sRole varchar(100),p_nInstID bigInt = 0)
