Question

我有一个gdb，其中包含一个从Frequency工具生成的表，我想将表添加到脚本中。如何使用搜索光标访问表格？

这是剧本：

print "START"
print""

arcpy.env.overwriteOutput = 1

fc = "D:\AVI \zl\zevel.gdb\point"

list_Fields = arcpy.ListFields(fc)
my_list = ("a","b","c")

for name in list_Fields:
    if name.name in my_list:
        print name.name
        output = r"D:\AVI \zl\zevel.gdb"
        tbl_name = output + r"\tbl"+"_"+ name.name
        print tbl_name

       arcpy.Frequency_analysis(fc,tbl_name,name.name)

      ### arcpy.SearchCursor....

我通常使用with语句调用游标，所以我不小心忘记关闭它们并导致数据锁定。

<?php
///////// Database Details , add  here  ////
$dbhost_name = "localhost";
$database = "test";  // Your database name
$username = "root";                  //  Login user id 
$password = "test";                  //   Login password
/////////// End of Database Details //////

//////// Do not Edit below /////////
try {
$dbo = new PDO('mysql:host=localhost;dbname='.$database, $username, $password);
} catch (PDOException $e) {
print "Error!: " . $e->getMessage() . "<br/>";
die();
}

?>

可替换地：

with arcpy.da.SearcCursor(fc, list_fields) as sr_cursor:
    for row in sr_cursor:
        # some code

希望这会有所帮助。有关更多信息，请查看arcgis资源页面： http://resources.arcgis.com/en/help/main/10.1/index.html#//002z0000001q000000
