ogr2ogr导出shapefile时出错

Question

我尝试在命令行界面中使用以下命令使用ogr2​​ogr从postgresql数据库中导出shapefile：

ogr2ogr -f "ESRI Shapefile" "C://ash//ash.shp" PG:"host=localhost user=postgres dbname=parcel password=admin -sql "SELECT * FROM'public'.'parcel' WHERE 'parcel'.'ParcelNoEng'=116"

错误显示：

ERROR 1: PQconnectdb failed.
missing "=" after "-sql" in connection info string

FAILURE:
