iPhone用のSQLiteアプリケーションを作成しました。iMacに配置されたSQLiteDBでSELECTをテストすると、すべてが正常に機能しますが、iPhoneでは行が返されません。
SELECT ID, SAP_PART_NR, SAP_DESC, MOQ, INC, NLT, DISCOUNT_CODE, AD_EURO, AD_USD, OEM_EURO, OEM_USD FROM Component WHERE SAP_PART_NR LIKE '%AWM423%' LIMIT 200
今奇妙な部分
iPhoneで以下の選択を使用すると、 SAP_PART_NRAWM42300Vで1つのレコードが返されます
SELECT ID, SAP_PART_NR, SAP_DESC, MOQ, INC, NLT, DISCOUNT_CODE, AD_EURO, AD_USD, OEM_EURO, OEM_USD FROM Component WHERE SAP_PART_NR LIKE '%AWM42%' LIMIT 200
iMacでテストすると、両方の選択で行が返されます（必要に応じて）
それはiPhone/SQliteのある種のバグですか？
私はそれを理解することができません....私の髪はすべて灰色になりました....:-(
